These capacitors are sometimes also called as a metalized capacitor or plastic capacitors. A Thin Film Capacitor is nothing but bipolar capacitors with plastic films as their dielectric. These films are either metalized or just placed in layers to form out a roll or a candy-like the rectangular shape.
Film capacitors are found for example in electric home appliances, electronic circuits in cars, industrial equipment, and power electronics devices. Depending on how the internal electrode is formed, film capacitors are divided into two main categories, namely foil electrode types and vapor deposition electrode (metallized film) types.
The performance of film capacitors differs, depending on the type of dielectric. It is therefore necessary to select the proper type according to the usage conditions. Wound type film capacitors with internal electrodes are made of metal foil (aluminum, tin, copper, etc.) sandwiched between plastic film layers and rolled up.
The plastic films listed below are used as dielectrics of film capacitors. Capacitors using PET as dielectric are also called mylar capacitors, after the brand name of a PET film made by DuPont. So-called styrol capacitors are film capacitors using polystyrene (styrol resin) as a dielectric.
There are two different types of plastic film capacitors, made with two different electrode configurations: Film/foil capacitors or metal foil capacitors are made with two plastic films as the dielectric. Each is layered with a thin metal foil, usually aluminum, as the electrodes.
Although the materials and construction techniques used for large power film capacitors are very similar to those used for ordinary film capacitors, capacitors with high to very high power ratings for applications in power systems and electrical installations are often classified separately, for historical reasons.
