Power Factor Correction Capacitor

Power factor correction capacitor belong to organic film capacitor class, its medium is polypropylene film, electrodes have metal host type and metal film type, the core of the rolled capacitor is wrapped with epoxy resin or encapsulated in plastic and metal case. Polypropylene capacitors made with metal film electrodes are called metallized polypropylene film capacitors.

Feature of power factor correction capacitor:

1.Wide range of capacity, can range from several thousand picofarads to tens of microfarads.
2.Good temperature resistance and high insulation resistance.
3.Metallized polypropylene film capacitors have good self-healing ability.
4.Small loss angle tangent value and good high frequency characteristics.
5.Small size and reliable operation.

Application of power factor correction capacitor:

1.Filter and noise suppression circuit
2.Pulse, logic and timing circuit
3.DC-blocking, by-passing and signal coupling in general communication‘s equipment
