Film capacitor
Iskra MIS

Capacitors for use in electronics are used mainly in electronic circuits. An application of a single capacitor type depends on the capacitor dielectric. Capacitor’s construction can include metallized dielectric (self-regenerative) or Al-film. Polyester, policarbonate and polypropylene films can be used as a dielectric. Capacitors with a polyester dielectric are used in electronic devices where wide temperature range of application is demanded and where special characteristics of electrical parameters are not demanded. Capacitors with a polypropylene dielectric are used in electronic circuits where are demanded as follows:

- high insulation resistance,
- negative and defined temperature coefficient,
- high pulse loading,
- low dielectric losses.

Metals like aluminium and alloys from aluminium and zinc are used for metallization of dielectrics.
