Like all capacitors, metallized film capacitors incorporate metal plates separated by a dielectric. Film capacitors are also known as plastic film, polymer film, or film dielectric capacitors. Film capacitors are inexpensive and come with a nearly limitless shelf life.
Film capacitors are versatile components that can be designed into power electronics for industries ranging from consumer and renewables to automotive, aerospace and military. These capacitors come with very specific advantages including non-polarity, a high insulation resistance, low dielectric losses and self-healing capability.
Capacitors made from metal-lized polypropylene film display low dielectric losses, high insula-tion resistance, low dielectric ab-sorption, high dielectric strength and deliver a robust, space-efficient solution. Long-term stability is also good. These Figure 1
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.
The type of electrode used determines whether the 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.

Before the introduction of plastic films, capacitors made by sandwiching a strip of wax-impregnated paper between strips of metal, and rolling the result into a cylinder–paper capacitors–were commonly used; their manufacture started in 1876, and they were used from the early 20th century as decoupling capacitors in telecommunications (telephony).
