Introduction
AVX Tantalum
AVX Paignton is the Divisional Headquarters for the Tantalum division which has manufacturing locations in Paignton in the UK, Biddeford in Maine, USA, Juarez in Mexico, Lanskroun in the Czech Republic and El Salvador. The Division takes its name from the raw material used to make its main products, Tantalum Capacitors. Tantalum is an element extracted from ores found alongside tin and niobium deposits; the major sources of supply are Canada, Brazil and Australasia. So for high volume tantalum capacitors with leading edge technology call us first - AVX your global partner.
TECHNOLOGY TRENDS
The amount of capacitance possible in a tantalum capacitor is directly related to the type of tantalum powder used to manufacture the anode. The graph following shows how the CV/g has steadily increased over time, thus allowing the production of larger and larger capacitances with the same physical volume. CV/g is the measure used to define the volumetric efficiency of a powder, a high CV/g means a higher capacitance from the same volume. These improvements in the powder have been achieved through close development with the material suppliers. AVX Tantalum is committed to driving the available technology forwards as is clearly identified by the new TACmicrochip technology and the standard codes under development. If you have any specific requirements, please contact your local AVX sales office for details on how AVX Tantalum can assist you in addressing your future requirements.

WORKING WITH THE CUSTOMER - ONE STOP SHOPPING
In line with our desire to become the number one supplier in the world for passive and interconnection components, AVX constantly feels the need to look forward and innovate. It is not good enough to market the best products, the customer must have access to a service system which suits their needs and benefits their business. The AVX `one stop shopping' concept is already beneficial in meeting the needs of major OEMs while worldwide partnerships with only the premier division of distributors aids the smaller user. Helping to market the breadth and depth of our electronic component line card and support our customers are a dedicated team of commercial sales people, applications engineers and product marketing managers. Their qualifications are hopefully always appropriate to your commercial need, but as higher levels of technical expertise are required, access directly to the appropriate department is seamless and transparent. Total quality starts and finishes with our customer service, and where cost and quality are perceived as given quantities the AVX service invariably has us selected as the preferred supplier. Facilities are equipped with instant worldwide computer and telecommunication links connected to every sales and production site worldwide. That ensures that our customers delivery requirements are consistently met wherever in the world they may be.

TPS Series
Low ESR
The TPS surface mount products have inherently low ESR (equivalent series resistance) and are capable of higher ripple current handling, producing lower ripple voltages, less power and heat dissipation than standard product for the most efficient use of circuit power. TPS has been designed, manufactured, and preconditioned for optimum performance in typical power supply applications. By combining the latest improvements in tantalum powder technology, improved manufacturing processes, and application specific preconditioning tests, AVX is able to provide a technologically superior alternative to the standard range.

Continued investment in R&D has resulted in AVX introducing revolutionary technology to the tantalum capacitor market. The new TACmicrochip breaks new ground with the unique structure allowing 10 times more capacitance to be packaged in the 0603 case size than is possible with traditional technology. Conventional molded tantalum technology results in an increase in ESR for each reduction in case size. Figure 1 shows a reduction in ESR performance of the TACmicrochip compared to the same case size if conventional technology were used. Figure 2 shows a major leap forward in F/mm3 performance. The CV values offered in the 0603 cannot be achieved using conventional molded technology. These features coupled with the temperature and voltage stability of tantalum, enable system designers to achieve equipment miniaturization without compromising performance, making TACmicrochip the optimum choice for size critical applications.

Technical Summary and Application Guidelines
INTRODUCTION
Tantalum capacitors are manufactured from a powder of pure tantalum metal. The typical particle size is between 2 and 10 m. Rearranging this equation gives:
A= Cd or
4000FV
10000FV
Figure 1.
20000FV
The powder is compressed under high pressure around a Tantalum wire to form a `pellet' (known as the Riser Wire). The riser wire is the anode connection to the capacitor. This is subsequently vacuum sintered at high temperature (typically 1500 - 2000C). This helps to drive off any impurities within the powder by migration to the surface. During sintering the powder becomes a sponge like structure with all the particles interconnected in a huge lattice. This structure is of high mechanical strength and density, but is also highly porous giving a large internal surface area (see Figure 2). The larger the surface area the larger the capacitance. Thus high CV (capacitance/voltage product) powders, which have a low average particle size, are used for low voltage, high capacitance parts. The figure below shows typical powders. Note the very great difference in particle size between the powder CVs. By choosing which powder is used to produce each capacitance/voltage rating the surface area can be controlled. The following example uses a 22F 25V capacitor to illustrate the point.
A C= o r d
thus for a 22F/25V capacitor the surface area is 150 square centimeters, or nearly half the size of this page. The dielectric is then formed over all the tantalum surfaces by the electrochemical process of anodization. To achieve this, the `pellet' is dipped into a very weak solution of phosphoric acid. The dielectric thickness is controlled by the voltage applied during the forming process. Initially the power supply is kept in a constant current mode until the correct thickness of dielectric has been reached (that is the voltage reaches the `forming voltage'), it then switches to constant voltage mode and the current decays to close to zero.
Figure 2. Sintered Tantalum
The chemical equations describing the process are as follows: Anode: Cathode: 2 Ta 2 Ta5+ + 10 e 2 Ta5+ 10 OH- Ta2O5 + 5 H2O 10 H2O - 10 e 5H2 + 10 OH-
where
o is the dielectric constant of free space
(8.855 x 10-12 Farads/m) r is the relative dielectric constant for Tantalum Pentoxide (27) d is the dielectric thickness in meters (for a typical 25V part) C is the capacitance in Farads A is the surface area in meters
The oxide forms on the surface of the Tantalum but it also grows into the metal. For each unit of oxide two thirds grows out and one third grows in. It is for this reason that there is a limit on the maximum voltage rating of Tantalum capacitors with present technology powders (see Figure 3). The dielectric operates under high electrical stress. Consider a 22F 25V part: Formation voltage = Formation Ratio x Working Voltage = 4 x 25 = 100 Volts

The next stage is the production of the cathode plate. This is achieved by pyrolysis of Manganese Nitrate into Manganese Dioxide. The `pellet' is dipped into an aqueous solution of nitrate and then baked in an oven at approximately 250C to produce the dioxide coat. The chemical equation is: Mn (NO3)2 Mn O2 + 2NO2
This process is repeated several times through varying specific densities of nitrate to build up a thick coat over all internal and external surfaces of the `pellet', as shown in Figure 4. The `pellet' is then dipped into graphite and silver to provide a good connection to the Manganese Dioxide cathode plate. Electrical contact is established by deposition of carbon onto the surface of the cathode. The carbon is then coated with a conductive material to facilitate connection to the cathode termination. Packaging is carried out to meet individual specifications and customer requirements. This manufacturing technique is adhered to for the whole range of AVX tantalum capacitors, which can be subdivided into four basic groups: Chip / Resin dipped / Rectangular boxed / Axial. Further information on the production of Tantalum Capacitors can be obtained from the technical paper "Basic Tantalum Technology", by John Gill, available from your local AVX representative.

Technical Summary and Application Guidelines
SECTION 1 ELECTRICAL CHARACTERISTICS AND EXPLANATION OF TERMS 1.1 CAPACITANCE
1.1.1 Rated capacitance (CR).
This is the nominal rated capacitance. For tantalum capacitors it is measured as the capacitance of the equivalent series circuit at 20C using a measuring bridge supplied by a 0.5Vpk-pk 120Hz sinusoidal signal, free of harmonics with a maximum bias of 2.2Vd.c.
1.2 VOLTAGE
1.2.1 Rated d.c. voltage (VR)
This is the rated d.c. voltage for continuous operation at 85C.
1.2.2 Category voltage (VC)
1.1.2 Capacitance tolerance.
This is the permissible variation of the actual value of the capacitance from the rated value. For additional reading, please consult the AVX technical publication "Capacitance Tolerances for Solid Tantalum Capacitors".
This is the maximum voltage that may be applied continuously to a capacitor. It is equal to the rated voltage up to +85C, beyond which it is subject to a linear derating, to 2/3 VR at 125C.
1.1.3 Temperature dependence of capacitance.
The capacitance of a tantalum capacitor varies with temperature. This variation itself is dependent to a small extent on the rated voltage and capacitor size.
1.2.3 Surge voltage (VS)
This is the highest voltage that may be applied to a capacitor for short periods of time. The surge voltage may be applied up to 10 times in an hour for periods of up to 30 seconds at a time. The surge voltage must not be used as a parameter in the design of circuits in which, in the normal course of operation, the capacitor is periodically charged and discharged.

1.1.4 Frequency dependence of the capacitance.
The effective capacitance decreases as frequency increases. Beyond 100KHz the capacitance continues to drop until resonance is reached (typically between 0.5 - 5MHz depending on the rating). Beyond the resonant frequency the device becomes inductive.

1.2.4 Effect of surges
The solid Tantalum capacitor has a limited ability to withstand voltage and current surges. This is in common with all other electrolytic capacitors and is due to the fact that they operate under very high electrical stress across the dielectric. For example a 25 volt capacitor has an Electrical Field of 147 KV/mm when operated at rated voltage.

Technical Summary and Application Guidelines
It is important to ensure that the voltage across the terminals of the capacitor never exceeds the specified surge voltage rating. Solid tantalum capacitors have a self healing ability provided by the Manganese Dioxide semiconducting layer used as the negative plate. However, this is limited in low impedance applications. In the case of low impedance circuits, the capacitor is likely to be stressed by current surges. Derating the capacitor by 50% or more increases the reliability of the component. (See Figure 2 page 37). The "AVX Recommended Derating Table" (page 38) summarizes voltage rating for use on common voltage rails, in low impedance applications. In circuits which undergo rapid charge or discharge a protective resistor of 1/V is recommended. If this is impossible, a derating factor of up to 70% should be used. In such situations a higher voltage may be needed than is available as a single capacitor. A series combination should be used to increase the working voltage of the equivalent capacitor: For example two 22F 25V parts in series is equivalent to one 11F 50V part. For further details refer to J.A. Gill's paper "Investigation into the effects of connecting Tantalum capacitors in series", available from AVX offices worldwide. The peak reverse voltage applied to the capacitor must not exceed: 10% of the rated d.c. working voltage to a maximum of 1.0v at 25C 3% of the rated d.c. working voltage to a maximum of 0.5v at 85C 1% of the category d.c. working voltage to a maximum of 0.1v at 125C
1.2.6 Superimposed A.C. Voltage (Vr.m.s.) Ripple Voltage.
This is the maximum r.m.s. alternating voltage; superimposed on a d.c. voltage, that may be applied to a capacitor. The sum of the d.c. voltage and peak value of the super-imposed a.c. voltage must not exceed the category voltage, Vc. Full details are given in Section 2.
1.2.7 Forming voltage.
This is the voltage at which the anode oxide is formed. The thickness of this oxide layer is proportional to the formation voltage for a tantalum capacitor and is a factor in setting the rated voltage.
NOTE:
While testing a circuit (e.g. at ICT or functional) it is likely that the capacitors will be subjected to large voltage and current transients, which will not be seen in normal use. These conditions should be borne in mind when considering the capacitor's rated voltage for use. These can be controlled by ensuring a correct test resistance is used.
1.3 DISSIPATION FACTOR AND TANGENT OF LOSS ANGLE (TAN )
1.3.1 Dissipation factor (D.F.).
Dissipation factor is the measurement of the tangent of the loss angle (tan ) expressed as a percentage. The measurement of DF is carried out using a measuring bridge which supplies a 0.5Vpk-pk 120Hz sinusoidal signal, free of harmonics with a maximum bias of 2.2Vdc. The value of DF is temperature and frequency dependent. Note: For surface mounted products the maximum allowed DF values are indicated in the ratings table and it is important to note that these are the limits met by the component AFTER soldering onto the substrate.
1.2.5 Reverse voltage and Non-Polar operation.
The values quoted are the maximum levels of reverse voltage which should appear on the capacitors at any time. These limits are based on the assumption that the capacitors are polarized in the correct direction for the majority of their working life. They are intended to cover short term reversals of polarity such as those occurring during switching transients of during a minor portion of an impressed waveform. Continuous application of reverse voltage without normal polarization will result in a degradation of leakage current. In conditions under which continuous application of a reverse voltage could occur two similar capacitors should be used in a back-to-back configuration with the negative terminations connected together. Under most conditions this combination will have a capacitance one half of the nominal capacitance of either capacitor. Under conditions of isolated pulses or during the first few cycles, the capacitance may approach the full nominal value. The reverse voltage ratings are designed to cover exceptional conditions of small level excursions into incorrect polarity. The values quoted are not intended to cover continuous reverse operation.
1.3.2 Tangent of Loss Angle (tan ).
This is a measurement of the energy loss in the capacitor. It is expressed as tan and is the power loss of the capacitor divided by its reactive power at a sinusoidal voltage of specified frequency. Terms also used are power factor, loss factor and dielectric loss. Cos (90 - ) is the true power factor. The measurement of tan is carried out using a measuring bridge which supplies a 0.5Vpk-pk 120Hz sinusoidal signal, free of harmonics with a maximum bias of 2.2Vdc.

1.3.3 Frequency dependence of Dissipation Factor.
Dissipation Factor increases with frequency as shown in the typical curves:

1.4.2 Equivalent Series Resistance, ESR.
Resistance losses occur in all practical forms of capacitors. These are made up from several different mechanisms, including resistance in components and contacts, viscous forces within the dielectric and defects producing bypass current paths. To express the effect of these losses they are considered as the ESR of the capacitor. The ESR is frequency dependent and can be found by using the relationship; tan ESR = 2fC Where f is the frequency in Hz, and C is the capacitance in farads. The ESR is measured at 20C and 100kHz. ESR is one of the contributing factors to impedance, and at high frequencies (100kHz and above) it becomes the dominant factor. Thus ESR and impedance become almost identical, impedance being only marginally higher.

1.4.3 Frequency dependence of Impedance and ESR.
ESR and Impedance both increase with decreasing frequency. At lower frequencies the values diverge as the extra contributions to impedance (due to the reactance of the capacitor) become more significant. Beyond 1MHz (and beyond the resonant point of the capacitor) impedance again increases due to the inductance of the capacitor.

1.4.1 Impedance, Z.
This is the ratio of voltage to current at a specified frequency. Three factors contribute to the impedance of a tantalum capacitor; the resistance of the semiconductor layer; the capacitance value and the inductance of the electrodes and leads. At high frequencies the inductance of the leads becomes a limiting factor. The temperature and frequency behavior of these three factors of impedance determine the behavior of the impedance Z. The impedance is measured at 20C and 100kHz.

1.5.3 Voltage dependence of the leakage current.
The leakage current drops rapidly below the value corresponding to the rated voltage VR when reduced voltages are applied. The effect of voltage derating on the leakage current is shown in the graph. This will also give a significant increase in the reliability for any application. See Section 3.1 for details.

The leakage current is dependent on the voltage applied, the elapsed time since the voltage was applied and the component temperature. It is measured at +20C with the rated voltage applied. A protective resistance of 1000 is connected in series with the capacitor in the measuring circuit. Three to five minutes after application of the rated voltage the leakage current must not exceed the maximum values indicated in the ratings table. These are based on the formulae 0.01CV or 0.5A (whichever is the greater). Reforming of tantalum capacitors is unnecessary even after prolonged storage periods without the application of voltage.

1.5.2 Temperature dependence of the leakage current.
The leakage current increases with higher temperatures, typical values are shown in the graph. For operation between 85C and 125C, the maximum working voltage must be derated and can be found from the following formula. Vmax = 1- (T - 85) x VRvolts, where T is the required 125 operating temperature.

SECTION 2 A.C. OPERATION, RIPPLE VOLTAGE AND RIPPLE CURRENT 2.1 RIPPLE RATINGS (A.C.)
In an a.c. application heat is generated within the capacitor by both the a.c. component of the signal (which will depend upon the signal form, amplitude and frequency), and by the d.c. leakage. For practical purposes the second factor is insignificant. The actual power dissipated in the capacitor is calculated using the formula: P= I2 R and rearranged to I = (PR) .....(Eq. 1) and substituting where I R E P Z P= E R Z2 = rms ripple current, amperes = equivalent series resistance, ohms = rms ripple voltage, volts = power dissipated, watts = impedance, ohms, at frequency under consideration
2
Where P is the maximum permissible power dissipated as listed for the product under consideration (see tables). However care must be taken to ensure that: 1. The d.c. working voltage of the capacitor must not be exceeded by the sum of the positive peak of the applied a.c. voltage and the d.c. bias voltage. 2. The sum of the applied d.c. bias voltage and the negative peak of the a.c. voltage must not allow a voltage reversal in excess of the "Reverse Voltage".
Historical ripple calculations.
Previous ripple current and voltage values were calculated using an empirically derived power dissipation required to give a 10C rise of the capacitors body temperature from room temperature, usually in free air. These values are shown in Table I. Equation 1 then allows the maximum ripple current to be established, and Equation 2, the maximum ripple voltage. But as has been shown in the AVX article on thermal management by I. Salisbury, the thermal conductivity of a Tantalum chip capacitor varies considerably depending upon how it is mounted.

Technical Summary and Application Guidelines
A piece of equipment was designed which would pass sine and square wave currents of varying amplitudes through a biased capacitor. The temperature rise seen on the body for the capacitor was then measured using an infra-red probe. This ensured that there was no heat loss through any thermocouple attached to the capacitor's surface. Results for the C, D and E case sizes

Power (Watts)
Several capacitors were tested and the combined results are shown here. All these capacitors were measured on FR4 board, with no other heatsinking. The ripple was supplied at various frequencies from 1KHz to 1MHz. As can be seen in the figure above, the average Pmax value for the C case capacitors was 0.11 Watts. This is the same as that quoted in Table I. The D case capacitors gave an average Pmax value 0.125 Watts. This is lower than the value quoted in the Table I by 0.025 Watts. The E case capacitors gave an average Pmax of 0.200 Watts which was much higher than the 0.165 Watts from Table I. If a typical capacitor's ESR with frequency is considered, e.g. figure below, it can be seen that there is variation. Thus for a set ripple current, the amount of power to be dissipated by the capacitor will vary with frequency. This is clearly shown in figure in top of next column, which shows that the surface temperature of the unit rises less for a given value of ripple current at 1MHz than at 100KHz. The graph below shows a typical ESR variation with frequency. Typical ripple current versus temperature rise for 100KHz and 1MHz sine wave inputs.

A square wave is the sum of an infinite series of sine waves at all the odd harmonics of the square waves fundamental frequency. The equation which relates is:
ISquare = Ipksin (2) + Ipk sin (6) + Ipk sin (10) + Ipk sin (14) +...
Thus the special components are:
Frequency 200 KHz 600 KHz 1 MHz 1.4 MHz Peak-to-peak current (Amps) 2.000 0.667 0.400 0.286 RMS current (Amps) 0.707 0.236 0.141 0.101
Let us assume the capacitor is a TAJD686M006 Typical ESR measurements would yield.
Frequency 200 KHz 600 KHz 1 MHz 1.4 MHz Typical ESR (Ohms) 0.120 0.115 0.090 0.100 Power (Watts) Irms2 x ESR 0.060 0.006 0.002 0.001
ESR (Ohms)

Thus the total power dissipation would be 0.069 Watts. From the D case results shown in figure top of previous column, it can be seen that this power would cause the capacitors surface temperature to rise by about 5C.

Technical Summary and Application Guidelines
2.2 Thermal Management
The heat generated inside a tantalum capacitor in a.c. operation comes from the power dissipation due to ripple current. It is equal to I2R, where I is the rms value of the current at a given frequency, and R is the ESR at the same frequency with an additional contribution due to the leakage current. The heat will be transferred from the outer surface by conduction. How efficiently it is transferred from this point is dependent on the thermal management of the board. The power dissipation ratings given in Section 2.1 are based on free-air calculations. These ratings can be approached if efficient heat sinking and/or forced cooling is used. In practice, in a high density assembly with no specific thermal management, the power dissipation required to give a 10C rise above ambient may be up to a factor of 10 less. In these cases, the actual capacitor temperature should be established (either by thermocouple probe or infra-red scanner) and if it is seen to be above this limit it may be necessary to specify a lower ESR part or a higher voltage rating. Please contact application engineering for details or contact the AVX technical publication entitled "Thermal Management of Surface Mounted Tantalum Capacitors" by Ian Salisbury.

SECTION 3 RELIABILITY AND CALCULATION OF FAILURE RATE 3.1 STEADY-STATE
Tantalum Dielectric has essentially no wear out mechanism and in certain circumstances is capable of limited self healing. However, random failures can occur in operation. The failure rate of Tantalum capacitors will decrease with time and not increase as with other electrolytic capacitors and other electronic components.

If the operating temperature is below the rated temperature for the capacitor then the operating reliability will be improved as shown in Figure 3. This graph gives a correction factor FT for any temperature of operation.

Figure 1. Tantalum Reliability Curve
The useful life reliability of the Tantalum capacitor is affected by three factors. The equation from which the failure rate can be calculated is: F = FU x FT x FR x FB where FU is a correction factor due to operating voltage/voltage derating FT is a correction factor due to operating temperature FR is a correction factor due to circuit series resistance FB is the basic failure rate level. For standard Tantalum product this is 1%/1000 hours

Circuit Impedance.
All solid tantalum capacitors require current limiting resistance to protect the dielectric from surges. A series resistor is recommended for this purpose. A lower circuit impedance may cause an increase in failure rate, especially at temperatures higher than 20C. An inductive low impedance circuit may apply voltage surges to the capacitor and similarly a non-inductive circuit may apply current surges to the capacitor, causing localized over-heating and failure. The recommended impedance is 1 per volt. Where this is not feasible, equivalent voltage derating should be used (See MIL HANDBOOK 217E). The graph, Figure 4, shows the correction factor, FR, for increasing series resistance.
Operating voltage/voltage derating.
If a capacitor with a higher voltage rating than the maximum line voltage is used, then the operating reliability will be improved. This is known as voltage derating. The graph, Figure 2, shows the relationship between voltage derating (the ratio between applied and rated voltage) and the failure rate. The graph gives the correction factor FU for any operating voltage.

As can clearly be seen from the results of this experiment, the more derating applied by the user, the less likely the probability of a surge failure occurring. It must be remembered that these results were derived from a highly accelerated surge test machine, and failure rates in the low ppm are more likely with the end customer. A commonly held misconception is that the leakage current of a Tantalum capacitor can predict the number of failures which will be seen on a surge screen. This can be disproved by the results of an experiment carried out at AVX on 47F 10V surface mount capacitors with different leakage currents. The results are summarized in the table below.
Example calculation
Consider a 12 volt power line. The designer needs about 10F of capacitance to act as a decoupling capacitor near a video bandwidth amplifier. Thus the circuit impedance will be limited only by the output impedance of the board's power unit and the track resistance. Let us assume it to be about 2 Ohms minimum, i.e. 0.167 Ohms/Volt. The operating temperature range is -25C to +85C. If a 10F 16 Volt capacitor was designed in the operating failure rate would be as follows. a) FT = 1.0 @ 85C b) FR = 0.85 @ 0.167 Ohms/Volt c) FU = 0.08 @ applied voltage/rated voltage = 75% Thus FB = 1.0 x 0.85 x 0.08 x 1 = 0.068%/1000 Hours If the capacitor was changed for a 20 volt capacitor, the operating failure rate will change as shown. FU = 0.018 @ applied voltage/rated voltage = 60% FB = 1.0 x 0.85 x 0.018 x 1 = 0.0153%/1000 Hours
Leakage current vs number of surge failures

Again, it must be remembered that these results were derived from a highly accelerated surge test machine, and failure rates in the low ppm are more likely with the end customer.

3.2 Dynamic.
As stated in Section 1.2.4, the solid Tantalum capacitor has a limited ability to withstand voltage and current surges. Such current surges can cause a capacitor to fail. The expected failure rate cannot be calculated by a simple formula as in the case of steady-state reliability. The two parameters under the control of the circuit design engineer known to reduce the incidence of failures are derating and series resistance. The table below summarizes the results of trials carried out at AVX with a piece of equipment which has very low series resistance with no voltage derating applied. That is the capacitor was tested at its rated voltage.
For further details on surge in Tantalum capacitors refer to J.A. Gill's paper "Surge in solid Tantalum capacitors", available from AVX offices worldwide. An added bonus of increasing the derating applied in a circuit, to improve the ability of the capacitor to withstand surge conditions, is that the steady-state reliability is improved by up to an order. Consider the example of a 6.3 volt capacitor being used on a 5 volt rail. The steady-state reliability of a Tantalum capacitor is affected by three parameters; temperature, series resistance and voltage derating. Assume 40C operation and 0.1 Ohms/Volt series resistance.

Technical Summary and Application Guidelines
The capacitors reliability will therefore be: Failure rate = FU x FT x FR x 1%/1000 hours = 0.15 x 0.1 x 1 x 1%/1000 hours = 0.015%/1000 hours If a 10 volt capacitor was used instead, the new scaling factor would be 0.006, thus the steady-state reliability would be: Failure rate = FU x FT x FR x 1%/1000 hours = 0.006 x 0.1 x 1 x 1%/1000 hours = 6 x 10-4 %/1000 hours
SECTION 4 APPLICATION GUIDELINES FOR TANTALUM CAPACITORS
So there is an order improvement in the capacitors steadystate reliability. ture and is designed to ensure that the temperature of the internal construction of the capacitor does not exceed 220C. Preheat conditions vary according to the reflow system used, maximum time and temperature would be 10 minutes at 150C. Small parametric shifts may be noted immediately after reflow, components should be allowed to stabilize at room temperature prior to electrical testing. Both TAJ and TAZ series are designed for reflow and wave soldering operations. In addition TAZ is available with gold terminations compatible with conductive epoxy or gold wire bonding for hybrid assemblies.
Soldering Conditions and Board Attachment.
The soldering temperature and time should be the minimum for a good connection. A suitable combination for wavesoldering is 230 - 250C for 3 - 5 seconds. For vapor phase or infra-red reflow soldering the profile below shows allowable and dangerous time/temperature combinations. The profile refers to the peak reflow tempera-

Under the CECC 00 802 International Specification, AVX Tantalum capacitors are a Class A component. The capacitors can therefore be subjected to one IR reflow, one wave solder and one soldering iron cycle. If more aggressive mounting techniques are to be used please consult AVX Tantalum for guidance.

5.6 Soldering Conditions
Dip soldering is permissible provided the solder bath temperature is 270C, the solder time < 3 seconds and the circuit board thickness 1.0mm.
Dimensions PS (Pad Separation) and PW (Pad Width) are calculated using dimensions x and z. Dimension y may vary, depending on whether reflow or wave soldering is to be performed. For reflow soldering, dimensions PL (Pad Length), PW (Pad Width), and PSL (Pad Set Length) have been calculated. For wave soldering the pad width (PWw) is reduced to less than the termination width to minimize the amount of solder pick up while ensuring that a good joint can be produced.
NOTE: These recommendations (also in compliance with EIA) are guidelines only. With care and control, smaller footprints may be considered for reflow soldering.
5.7 Installation Instructions
The upper temperature limit (maximum capacitor surface temperature) must not be exceeded even under the most unfavorable conditions when the capacitor is installed. This must be considered particularly when it is positioned near components which radiate heat strongly (e.g. valves and power transistors). Furthermore, care must be taken, when bending the wires, that the bending forces do not strain the capacitor housing.

Questions & Answers
The two resistors are used to ensure that the leakage currents of the capacitors does not affect the circuit reliability, by ensuring that all the capacitors have half the working voltage across them. Question: What are the advantages of tantalum over other capacitor technologies? Answer: 1. Tantalum capacitors have high volumetric efficiency. 2. Electrical performance over temperature is very stable. 3. They have a wide operating temperature range -55 degrees C to +125 degrees C. 4. They have better frequency characteristics than aluminum electrolytics. 5. No wear out mechanism. Because of their construction, solid tantalum capacitors do not degrade in performance or reliability over time. Question: How does TPS differ from your standard 33F product? 16.5F 25V Answer: TPS has been designed from the initial anode 50V production stages for power supply applications. Special 33F manufacturing processes provide the most robust capacitor 25V dielectric by maximizing the volumetric efficiency of the package. After manufacturing, parts are conditioned by effective capacitance will be halved, so for greater than 60F, being subjected to elevated temperature overvoltage burn in four such series combinations are required, as shown. applied for a minimum of two hours. Parts are monitored on a 100% basis for their direct current leakage performance at elevated temperatures. Parts are then subjected to a low impedance current surge. This current surge is performed on a 100% basis with each capacitor individually monitored. 33F 66F At this stage, the capacitor undergoes 100% test for 25V capacitance, Dissipation Factor, leakage current, and 50V 100 KHz ESR to TPS requirements. Question: If the part is rated as a 25 volt part and you have current surged it, why can't I use it at 25 volts in a low In order to ensure reliable operation, the capacitors should impedance circuit? be connected as shown below to allow current sharing of Answer: The high volumetric efficiency obtained using the ac noise and ripple signals. This prevents any one tantalum technology is accomplished by using an extremely capacitor heating more than its neighbors and thus being thin film of tantalum pentoxide as the dielectric. Even the weak link in the chain. an application of the relatively low voltage of 25 volts will + produce a large field strength as seen by the dielectric.

The equation for determining the amount of 100K surface area for a capacitor is as follows: Some commonly asked questions regarding Tantalum Capacitors: Question: If I use several tantalum capacitors in serial/parallel combinations, how can I ensure equal current and voltage sharing? Answer: Connecting two or more capacitors in series and parallel combinations allows almost any value and rating to be constructed for use in an application. For example, a capacitance of more than 60F is required in a circuit for stable operation. The working voltage rail is 24 volts dc with a superimposed ripple of 1.5 volts at 120 Hz. The maximum voltage seen by the capacitor is Vdc + Vac=25.5V Applying the 50% derating rule tells us that a 50V capacitor is required. Connecting two 25V rated capacitors in series will give the required capacitance voltage rating, but the

Questions & Answers
C = ( (E) (E) (A) ) / d A = ( (C) (d) ) /( (E)(E) ) A = ( (22 x 10-6) (170 x 10-9) ) / ( (8.85 x 10-12) (27) ) A = 0.015 square meters (150 square centimeters) Where C = Capacitance in farads A = Dielectric (Electrode) Surface Area (m2) d = Dielectric thickness (Space between dielectric) (m) E = Dielectric constant (27 for tantalum) E = Dielectric Constant relative to a vacuum (8.855 x 10-12 Farads x m-1) To compute the field voltage potential felt by the dielectric we use the following logic. Dielectric formation potential = Formation Ratio x Working Voltage = 4 x 25 Formation Potential = 100 volts Dielectric (Ta2O5) Thickness (d) is 1.7 x 10-9 Meters Per Volt d = 0.17 meters Electric Field Strength = Working Voltage / d = (25 / 0.17 meters) = 147 Kilovolts per millimeter = 147 Megavolts per meter No matter how pure the raw tantalum powder or the precision of processing, there will always be impurity sites in the dielectric. We attempt to stress these sites in the factory with overvoltage surges, and elevated temperature burn in so that components will fail in the factory and not in your product. Unfortunately, within this large area of tantalum pentoxide, impurity sites will exist in all capacitors. To minimize the possibility of providing enough activation energy for these impurity sites to turn from an amorphous state to a crystalline state that will conduct energy, series resistance and derating is recommended. By reducing the electric field within the anode at these sites, the tantalum capacitor has increased reliability. Tantalums differ from other electrolytics in that charge transients are carried by electronic conduction rather than absorption of ions. Question: What negative transients can Solid Tantalum Capacitors operate under? Answer: The reverse voltage ratings are designed to cover exceptional conditions of small level excursions into incorrect polarity. The values quoted are not intended to cover continuous reverse operation. The peak reverse voltage applied to the capacitor must not exceed: 10% of rated DC working voltage to a maximum of 1 volt at 25C. 3% of rated DC working voltage to a maximum of 0.5 volt at 85C. 1% of category DC working voltage to a maximum of 0.1 volt at 125C. Question: I have read that manufacturers recommend a series resistance of 0.1 ohm per working volt. You suggest we use 1 ohm per volt in a low impedance circuit. Why? Answer: We are talking about two very different sets of circuit conditions for those recommendations. The 0.1 ohm per volt recommendation is for steady-state conditions. This level of resistance is used as a basis for the series resistance variable in a 1% / 1000 hours 60% confidence level reference. This is what steady-state life tests are based on. The 1 ohm per volt is recommended for dynamic conditions which include current in-rush applications such as inputs to power supply circuits. In many power supply topologies where the di/dt through the capacitor(s) is limited, (such as most implementations of buck (current mode), forward converter, and flyback), the requirement for series resistance is decreased. Question: How long is the shelf life for a tantalum capacitor? Answer: Solid tantalum capacitors have no limitation on shelf life. The dielectric is stable and no reformation is required. The only factors that affect future performance of the capacitors would be high humidity conditions and extreme storage temperatures. Solderability of solder coated surfaces may be affected by storage in excess of one year under temperatures greater than 40C or humidities greater than 80% relative humidity. Terminations should be checked for solderability in the event an oxidation develops on the solder plating. Question: Do you recommend the use of tantalum capacitors on the input side of DC-DC converters? Answer: No. Typically the input side of a converter is fed from the voltage sources which are not regulated and are of nominally low impedance. Examples would be Nickel-MetalHydride batteries, Nickel-Cadmium batteries, etc., whose internal resistance is typically in the low milliohm range.
