Film Capacitors

The initial stage of manufacturing a film capacitor is to start with plastic film, or paper and film, and roll it up with thin aluminium or copper foil. As the film may contain microscopic flaws (and the paper always does), multiple layers of thin film is required rather than 1 layer of a thicker film.

Aluminum Electrolytic Capacitors

As is the case with all capacitors, an aluminum electrolytic capacitor comprises two electrically con-ductive material layers that are separated by a dielectric layer. One electrode (the anode) is formed by an aluminum foil with an enlarged surface area. The oxide layer (Al2O3) that is built up on this is used as the dielectric.
