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