Film Capacitors

Film capacitors, also called Polypropylene Film Capacitors, are typically used when a very low dissipation factor and higher power handling capacity capacitors are needed. This type of capacitor is constructed using a thin film of dielectric material (polypropylene) coated on an aluminum foil electrode to form a flat, winding-type structure. A metalized foil is used to create anm conduction path between the two electrodes. The construction results in a robust capacitor with excellent performance characteristics, especially in high-frequency applications.

Type F17724682204 application field

The F17724682204 film capacitor is widely used in the electronic circuit industry, due to its superior performance, such as its low frequency self-resonance, high-temperature stability and high-frequency loss. It is especially suitable for audio, noise suppression, car audio systems, fire alarm systems, HIFI, digital broadcast equipment, audio-video equipment, switching power supplies and inverters.

Type F17724682204 Working Principle

The working principle of a F17724682204 film capacitor is based on the Capacitance principle. In a metal-insulator-metal structure, when an electrical voltage is applied between the two electrodes, a charge is established across the capacitor, which is proportional to the plate surface area, the distance between them and the relative permittivity of the dielectric material. The capacitance of the capacitor is determined by the size of the dielectric, its electrical properties and the distance between the electrodes. The capacitor will store energy when a voltage is applied between the electrodes and then slowly release it when the voltage is removed.

Conclusion

The F17724682204 film capacitor is a highly reliable capacitor with a superior performance when used in electronic circuits. Its low dissipation factor, high power handling capacity and excellent high-frequency properties makes it an ideal choice for use in audio, fire alarm systems, digital broadcast equipment, and switching power supplies and inverters. The working principle of the F17724682204 film capacitor is based on the Capacitance principle and the capacitance is determined by the size of the dielectric, its electrical properties and the distance between the electrodes.
