51 capacitor array capacitor array (ipc) avx capacitor arrays offer designers the opportunity to lower placement costs, increase assembly line output through lower component count per board and to reduce real estate requirements. reduced costs placement costs are greatly reduced by effectively placing one device instead of four or two. this results in increased throughput and translates into savings on machine time. inventory levels are lowered and further savings are made on solder materials, etc. space saving space savings can be quite dramatic when compared to the use of discrete chip capacitors. as an example, the 0508 4-element array offers a space reduction of >40% vs. 4 x 0402 discrete capacitors and of >70% vs. 4 x 0603 discrete capacitors. (this calculation is dependent on the spacing of the discrete components.) increased throughput assuming that there are 220 passive components placed in a mobile phone: a reduction in the passive count to 200 (by replacing discrete components with arrays) results in an increase in throughput of approximately 9%. a reduction of 40 placements increases throughput by 18%. for high volume users of cap arrays using the very latest placement equipment capable of placing 10 components per second, the increase in throughput can be very significant and can have the overall effect of reducing the number of place- ment machines required to mount components: if 120 million 2-element arrays or 40 million 4-element arrays were placed in a year, the requirement for placement equipment would be reduced by one machine. during a 20hr operational day a machine places 720k components. over a working year of 167 days the machine can place approximately 120 million. if 2-element arrays are mounted instead of discrete components, then the number of placements is reduced by a factor of two and in the scenario where 120 million 2-element arrays are placed there is a saving of one pick and place machine. smaller volume users can also benefit from replacing discrete components with arrays. the total number of place- ments is reduced thus creating spare capacity on placement machines. this in turn generates the opportunity to increase overall production output without further investment in new equipment. w2a (0508) capacitor arrays the 0508 4-element capacitor array gives a pcb space saving of over 40% vs four 0402 discretes and over 70% vs four 0603 discrete capacitors. w3a (0612) capacitor arrays the 0612 4-element capacitor array gives a pcb space saving of over 50% vs four 0603 discretes and over 70% vs four 0805 discrete capacitors. area = 7.0mm 2 (0.276 in 2 ) area = 3.95mm 2 (0.156 in 2 ) 5.0 (0.197) 1.4 (0.055) 1.0 (0.039) 2.1 (0.083) 1.88 (0.074) 4 pcs 0402 capacitors = 1 pc 0508 array area = 13.8mm 2 (0.543 in 2 ) area = 6.4mm 2 (0.252 in 2 ) 6.0 (0.236) 2.3 (0.091) 1.5 (0.059) 3.2 (0.126) 2.0 (0.079) 4 pcs 0603 capacitors = 1 pc 0612 array benefits of using capacitor arrays

56 capacitor array multi-value capacitor array (ipc) general description a recent addition to the array product range is the multi- value capacitor array. these devices combine two different capacitance values in standard cap array packages and are available with a maximum ratio between the two capacitance values of 100:1. the multi-value array is currently available in the 0405 and 0508 2-element styles and also in the 0612 4-element style. whereas to date avx capacitor arrays have been suited to applications where multiple capacitors of the same value are used, the multi-value array introduces a new flexibility to the range. the multi-value array can replace discrete capacitors of different values and can be used for broadband decoupling applications. the 0508 x 2 element multi-value array would be particularly recommended in this application. another application is filtering the 900/1800 or 1900mhz noise in mobile phones. the 0405 2-element, low capacitance value np0, (c0g) device would be suited to this application, in view of the space saving requirements of mobile phone manufacturers. advantages of the multi-value capacitor arrays enhanced performance due to reduced parasitic inductance when connected in parallel, not only do discrete capacitors of different values give the desired self-resonance, but an additional unwanted parallel resonance also results. this parallel resonance is induced between each capacitors self- resonant frequencies and produces a peak in impedance response. for decoupling and bypassing applications this peak will result in a frequency band of reduced decoupling and in filtering applications reduced attenuation. the multi-value capacitor array, combining capacitors in one unit, virtually eliminates the problematic parallel resonance, by minimizing parasitic inductance between the capacitors, thus enhancing the broadband decoupling/filtering performance of the part. reduced esr an advantage of connecting two capacitors in parallel is a significant reduction in esr. however, as stated above, using discrete components brings with it the unwanted side effect of parallel resonance. the multi-value cap array is an excellent alternative as not only does it perform the same function as parallel capacitors but also it reduces the uncertainty of the frequency response. 100 10 1 1000 frequency (mhz) 0 0.2 0.4 0.6 0.8 1 impedance (ohms) 2xdiscrete caps (0603) multi value cap (0508) cap (min/max) np0 x5r/x7r 0612 4-element 100/471 221/104 0508 2-element 100/471 221/104 0405 2-element 100/101 101/103 ? max. ratio between the two cap values is 1:100. ? the voltage of the higher capacitance value dictates the voltage of the multi-value part. ? only combinations of values within a specific dielectric range are possible. impedance vs frequency w style 2 case size 1 = 0405 2 = 0508 3 = 0612 a array 2 number of caps a failure rate y voltage z = 10v y = 16v 3 = 25v 5 = 50v 1 = 100v c dielectric a = np0 c = x7r d = x5r 102m 1st value capacitance code (in pf) 2 sig. digits + no. of zeros 104m 2nd value capacitance tolerance k = 10% m = 20% 2a packaging & quantity code 2a = 7" reel (4000) 4a = 13" reel (10000) 2f = 7" reel (1000) how to order (multi-value capacitor array - ipc) note: contact factory for availability of termination and tolerance options for specific part numbers. **rohs compliant t terminations t = plated ni and sn** z = flexiterm ? ** b = 5% min lead x = flexiterm ? with 5% min lead
