6 FAQs about [Characteristics of Metal Film Capacitors]
How can metallized film capacitors be optimized for specific applications?
Capacitor manufacturers can optimize the characteris-tics of metallized film capacitors for specific applications by selecting a suitable dielectric. For example, polyester films display good properties for general-purpose applications.
How do you know if a capacitor is a metalized film or foil?
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.
How do film capacitors work?
Film capacitors are build up by two electrodes (the capacitor plates) with plastic dielectric material in between. 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.
Why are film / foil capacitors used instead of metalized capacitors?
Due to their construction, very thick electrodes, film / foil capacitors can carry higher currents than metalized types, but are much larger in volume. These capacitors can not recover after a breakdown. Therefore In some constructions double side metalized plastic film is used as electrode to replace the foil.
What are the different types of plastic film capacitors?
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.
What materials are used in film capacitors?
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.
