ECW-F4114HL

Film Capacitors

A film capacitor is a type of capacitor that uses a thin plastic or paper film as the dielectric instead of the more common aluminum oxide, ceramic, or mica used in other types of capacitors. It is a part of the capacitor family that consists of the foil, ceramic, plastic film and paper dielectrics, and is made up of two thin pieces of metalized dielectric that are separated by air or gas. The two pieces are connected by a lead wire, or two separate pieces of foil are placed inside the same material.

Film capacitors tend to be less costly and more compact than other types of capacitors. The thin electrolyte dielectric (most commonly polyethylene terephthalate PET) is used to produce a high surface area, allowing for greater capacitance in a smaller package. They are common in electrical and electronic circuits for signal filtering and energy storage, and in AC power supplies for power factor correction.
