Electrical Characteristics Fields Application
Basically WIMA series have same electrical characteristics analogous through-hole WIMA capacitors. Compared ceramic tantalum dielectrics WIMA capacitors have number other outstanding qualities favourable pulse rise time dielectric absorption available high voltage series large capacitance spectrum stand high mechanical stress good long-term stability regards technical performance well quality reliability, WIMA series offer possibility cover nearly applications conventionally throughhole film capacitors with components. Furthermore, WIMA series used demanding capacitor applications which, past, through-hole components mandatory: measuring techniques oscillator circuits differentiating integrating circuits transformers sample hold circuits automotive electronics With WIMA programme available today, major part plastic film capacitors replaced WIMA components. field application ranges from standard coupling capacitors switch-mode power supplies filter charging capacitors with high voltage capacitance values, well telecommunications e.g. well-known telephone capacitor 1mF/250VDC.
Washing
Basically, plastic encapsuled components, irrespective brand cannot considered being hermetically sealed. They therefore only suitable industrial washing processes limited extent. During washing process, washing agents penetrate interior component capillary action through microcracks which might have occured. This dependent number parameters washing agents viscosity washing solvent temperature/time washing process mechanical washing aids such ultrasonic water pressure rinsing spraying pressure type washing agent used largely specific individual user often laid down manufacturer washing equipment. agressiveness washing agent used thus only judged appropriate test series relating each individual washing process. large, basic rule that washing process should carried gently possible.
Humidity Protection Bags
Taped WIMA capacitors shipped humidity protection bags according JEDEC standard, level (EMI/static-shielding bags conforming MIL-B 81705, Type Class Under controlled conditions components stored years more originally sealed bag. Opened packing units should consumed instantly resealed specific storage under controlled conditions.
Reliability
Taking account manufacturer`s guidelines compatible processing, WIMA stand same high quality reliability analogous through-hole WIMA series. technology metallized film capacitors used e.g. WIMA SMD-PET achieves best values fields application. expected value about: Furthermore production WIMA components subject regulations
Drying
During washing process, aqueous solutions penetrate component. This lead changes electrical parameters. Suitable drying measures should ensure that residual moisture traces washing substances left component.
