Film Capacitors Selection Guide: Types, Features, Applications
Film Capacitor Basics . 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.
What Are Film Capacitors?
Film capacitors or plastic film capacitors are non-polarized capacitors with an insulating plastic film as the dielectric. The dielectric films are drawn to a thin layer, provided with metallic electrodes and wound into a cylindrical winding.
