Learn more WhatsAppFigure 14: Illustration of the distinction between metal film and foil electrode styles in film capacitors. Film capacitors based on metal film electrodes have the advantage of being able to self-heal; the electrode material near a localized fault in the dielectric is thin enough to be vaporized by the leakage current caused by the fault, thus ...
Learn more WhatsAppFilm 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.
