Detailed description of the classification and characteristics of film capacitor(I)

Composite film capacitor

This capacitor selects two different kinds of film (or paper and film) to make composite medium. For example, a capacitor made of polystyrene film and polypropylene film, which is better than polystyrene capacitance, increases the strength and temperature of the capacitor and reduces the volume, but the temperature coefficient and loss of the capacitor are slightly worse.

Polyimide film capacitor

The electrical properties of the capacitor are similar to that of polyester capacitors, and the heat resistance, cold resistance and polytetrafluoroethylene capacitance are similar, and the resistance to radiation and combustion can be worked in bad environment.

Plastic film capacitor

At present, mass production of plastic film capacitors are polystyrene, polyethylene, polypropylene, PTFE, polyester (terylene), polycarbonate, composite film.
