Polypropylene film anti-interference capacitor

What is polypropylene film capacitor?

These capacitors are generally using polypropylene film as a dielectric, and these are used for high-frequency high power applications including heating, pulse power energy discharge application, and AC capacitors for electrical distribution. The film capacitor is widely used in different sector, because of their higher characteristics.

What are Polyphenylene sulfide film capacitors?

Polyphenylene sulfide film capacitors are film capacitors with dielectric made of the thermoplastic, organic, and partially crystalline polymer material Poly (p-phenylene sulfide) (PPS), trade name Torelina. They are only produced as metallized types.

What is a Polytetrafluoroethylene film capacitor?

Polytetrafluoroethylene film capacitors are made with a dielectric of the synthetic fluoropolymer polytetrafluoroethylene (PTFE), a hydrophobic solid fluorocarbon. They are manufactured both as metallized and as film/foil types, although poor adherence to the film makes metallization difficult. PTFE is often known by the DuPont trademark Teflon.

What is a polyester film capacitor?

Polyester film capacitors are film capacitors using a dielectric made of the thermoplastic polar polymer material polyethylene terephthalate (PET), trade names Hostaphan or Mylar, from the polyester family. They are manufactured both as metallized wound and stacked versions, as well as film/foil types.

Why are polypropylene film capacitors used in resonant circuits?

Polypropylene film capacitors are specified because of their low electrical losses and their nearly linear behavior over a very wide frequency range, for stability Class 1 applications in resonant circuits, comparable only with ceramic capacitors.
