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. The electrodes of film / foil capacitors have discrete metal foils with thicknesses of approximately 5 μm to 10 μm.
A film capacitor is a capacitor that uses polymer film as the dielectric. It is one recent example of a component that uses metalized film with the internal electrodes deposited to the film. Film capacitors can be classified by their structures and the types of dielectrics they contain.
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. Subcategories according to construction …
The term "film capacitor" generically refers to any device made using this sort of process, and the term "film" is in reference to the nature of the dielectric material used. When the term "metal" is used as a qualifier for "film" …
In 1979, AVX developed the first film capacitors with a controlled self-healing process by applying the metallic layer to the film in small patterns, rather than all over. This resulted in safer and more controlled power film capacitor performance, and allowed these products to be employed in higher-power applications.
