Metallized Capacitors in PCM 7.5 - 37.5 mm

WIMA capacitors for demanding requirements cover a wide range of capacitances and voltages and are available with Polyester, Polypropylene or Mixed Film dielectrics.

For metallized capacitors a thin metal coating serving as electrode is applied to the plastic film. This method makes it possible to produce capacitors with a very favourable capacitance/volume ratio. The WIMA MKS 4, with 220 µF/50 VDC, offers the highest capacitance rating in the WIMA range. A further specific characteristic of metallized capacitors is the excellent self-healing ability. In the case of an electric breakdown the applied metal layer evaporates. The affected area is isolated and the capacitor continues to function properly.

WIMA capacitors for stringent requirements are available with values ranging from 1000 pF through 220 µF with voltage ratings from 50 VDC through 2000 VDC. In accordance with customer requirements, larger box sizes can be supplied as 4-lead versions. Types with terminating plates can also be manufactured on request. The advantage of this method of construction, besides the improved mechanical stability of the component on the board, is the excellent electrical contact reliability.
