Film capacitors are passive components that use an extremely thin plastic film as a dielectric insulator. They are constructed of two pieces of plastic film wound into a cylindrical shape. The winding is attached to two unpolarized terminals, which represent the plates of a basic capacitor, and is then encapsulated for protection.
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.
Its structure is made of “Plastic Films.” These films are made to be very thin. Once the “Film drawing procedure” is done, the created film can be coated with a metal or left as is, depending on the use. The generic method of development for these capacitors begins with the removal of a thin layer of plastic film.
Film capacitors use PP (polypropylene), PET (polyethylene terephthalate), PPS (polyphenylene sulfide), PEN (polyethylene naphthalate), etc., as dielectric material, having higher insulation resistance compared with ceramic capacitors and aluminum electrolytic capacitors as well as higher capability of retaining stored electricity.
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.
