Afhankelijk van het type plastic film worden ze onderverdeeld in: condensatoren op basis van polyethyleen (ook bekend als Mylar condensatoren), polypropyleen condensatoren (ook bekend als PP condensatoren), polystyreen condensatoren (ook bekend als PS condensatoren) en polycarbonaat condensatoren.
The structure is the same as paper dielectric capacitor, and the dielectric is polyester or polystyrene, etc. Polyester film capacitor has high dielectric constant, small size, large capacity, good stability, and suitable for bypass capacitor. Polystyrene film capacitor, with low dielectric loss and high insulation resistance, but with high temperature coefficient, can be used in high frequency circuit.
Film capacitors can be divided into DC film capacitors and AC film capacitors: DC film capacitors are film capacitors working in circuits powered by DC power supply, which can be divided into four categories: general-purpose, power supply electromagnetic interference suppression, pulse and precision; AC film capacitors are film capacitors working in circuits powered by AC power supply, which can be divided into motor starting operation, power factor compensation, etc. Electrolytic capacitors: leaded aluminum electrolytic capacitors; bullhorn aluminum electrolytic capacitors; bolted aluminum electrolytic capacitors; solid state aluminum electrolytic capacitors.
