Film capacitors are build up by two electrodes (the capacitor plates) with plastic dielectric material in between. The type of electrode used determines whether the capacitor is a metalized film or film / foil type. In metalized types, the very thin electrode is evaporated on the plastic dielectric material.
Plastic film capacitors are generally subdivided into film/foil capacitors and metalized film capacitors. Film / foil capacitors basically consist of two metal foil electrodes that are separated by an insulating plastic film also called dielectric. The terminals are connected to the end-faces of the electrodes by means of welding or soldering.
Film capacitors' interior structure consists mainly of metal foil (or a foil obtained by metalizing plastic) used as the electrode plate and plastic used as the dielectric. This structure is obtained through a winding or stacking process. The various arrangements of foils and films result in different construction methods.
The characteristics of a film capacitor, and the situations in which the capacitor can be used, will vary greatly depending on the type of dielectric used. For example, a PP film capacitor provides excellent self-healing and high reliability, and is therefore often used in fields such as vehicle-mounted equipment and industry automation.

The type of electrode used determines whether the capacitor is a metalized film or film / foil type. In metalized types, the very thin electrode is evaporated on the plastic dielectric material. The thin metalized electrodes have a thickness of approximately 10 nm to 50 nm.
