Printed Circuit Board Materials: Type CWR11 is compatible with commonly used printed circuit board materials (alumina substrates, FR4, FR5, G10, PTFE-fluorocarbon and porcelanized steel). Attachment: Solder Paste: The recommended thickness of the solder paste after application is .007" .001" [.178mm .025mm]. Care should be exercised in selecting the solder paste. The metal purity should be as high as practical. The flux (in the paste) must be active enough to remove the oxides formed on the metallization prior to the exposure to soldering heat. In practice this can be aided by extending the solder preheat time at temperatures below the liquidous state of the solder. Soldering: Capacitors can be attached by conventional soldering techniques - vapor phase, infrared reflow, wave soldering and hot plate methods. The Soldering Profile chart shows maximum recommended time/temperature conditions for soldering. Attachment with a soldering iron is not recommended due to the difficulty of controlling temperature and time at temperature. Cleaning (Flux Removal) After Soldering: The CWR11 is compatible with all commonly used solvents such as TES, TMS, Prelete, Chlorethane, Terpene and aqueous cleaning media. However, CFC/ODS products are not used in the production of these devices and are not recommended. Solvents containing methylene chloride or other epoxy solvents should be avoided since these will attack the epoxy encapsulation material. When using ultrasonic cleaning, the board may resonate if the output power is too high. This vibration can cause cracking or a decrease in the adherence of the termination. DO NOT EXCEED 9W/l @ 40kHz for 2 minutes.
Power Dissipation in Watts @ + 25C as given in the table in Paragraph Number 5 (Power Dissipation).
RESR = The capacitor Equivalent Series Resistance at the specified frequency. Z= 2.1 The capacitor impedance at the specified frequency. 7.2
The sum of the peak AC voltage plus the DC voltage shall not exceed the DC voltage rating of the capacitor. The sum of the negative peak AC voltage plus the applied DC voltage shall not allow a voltage reversal exceeding 10% of the DC working voltage at + 25C. Reverse Voltage: These capacitors are capable of withstanding peak voltages in the reverse direction equal to 10% of the DC rating at + 25C, 5% of the DC rating at + 85C and 1% of the DC rating at + 125C. Temperature Derating: If these capacitors are to be operated at temperatures above + 25C, the permissible rms ripple current or voltage shall be calculated using the derating factors as shown:
Temperature + 25C + 85C + 125C Derating Factor 1.0 0.9 0.4

Recommended Mounting Pad Geometries: Proper mounting pad geometries are essential for successful solder connections. These dimensions are highly process sensitive and should be designed to minimize component rework due to unacceptable solder joints. The dimensional configurations shown are the recommended pad geometries for both wave and reflow soldering techniques. These dimensions are intended to be a starting point for circuit board designers and may be fine tuned if necessary based upon the peculiarities of the soldering process and/or circuit board design.
