WIMA capacitors in PCM 5 mm are available in metallized or film and foil versions with the dielectrics Polyester, Polypropylene, Polyphenylene-sulphide and Mixed film.

WIMA capacitors with a Polyester dielectric (PET) are suitable for general applications such as coupling, decoupling and by-passing. By making use of ultra thin film and appropriate manufacturing experience, it has been possible to achieve high capacitance values in very small boxe sizes. The WIMA MKS 2 for example is available with capacitance values up to 10 µF in 5 mm PCM.

Polypropylene capacitors (PP) are used in the high frequency field. This includes resonant circuits, power supplies, deflection circuits, oscillator circuits and audio equipment. WIMA Polypropylene capacitors in PCM 5 mm can also be supplied in high pulse film/foil versions with rated voltages up to 1000 VDC.

Mixed dielectric capacitors are used wherever linear behaviour versus temperature is required. This allows the replacement of the obsolete Polycarbonate capacitors in e.g. filters, memories, timers and balancers and also in automotive electronics and lighting industry.

Based on a temperature stable Polyphenylene-sulphide (PPS) film the WIMA MKI 2 range is designed for operating temperatures up to +140° C in e.g. automotive applications, lighting or sensor technology. Capacitors of this range feature a very low deviation of capacitance, dissipation factor and insulation resistance versus temperature.

Metallized capacitors stand out for their excellent self-healing properties and their very favourable capacitance/volume ratio. Film and foil capacitors have a high pulse load capacity due to their strong dimensioning.
