PPN are non-inductively wound polypropylene film dielectric and aluminum foil electrode with copper-clad steel leads and epoxy resin coated. They are suitable for blocking, by-pass coupling and temperature coppensation for applications in telecommunication, data processing, industrial instrumentation and automa.

In the electric AC circuit of 50Hz/60Hz, the capacitor provides a single-phase function to startup and operation of the electromotor. It is mainly used in electrical appliance like washing machine and water pump, and the electrical circuit of the gas discharge light bulb whose altitude height doesn't exceed 3000 meters. This product has advantages like small volume, light weight, stable capacitance, excellent self-recovery ability and long life cycle.
