Film Capacitors

BFC237515222 Application Field And Working Principle

Film capacitors, also known as film dielectric capacitors, plastic film capacitors or film foil capacitors, are so-called because they use a film as the dielectric. The types of film commonly used are polyester film, polypropylene film (PP), polyphenylene sulfide film (PPS), polycarbonate film (PC), polyphenylenether film (PEN) and polyvinylidene fluoride film (PVDF).

BFC237515222 is a polyester film capacitor with capacitance of 10uF, voltage of 475V and tolerance of ±10%. It is widely used in numerous electronic and electrical appliances, such as air-conditioning equipment, audio simulation equipment, lighting products and automotive equipment. Its core material is also made of metalized polyester film, which has outstanding properties such as good insulation, long service life and low temperature drift.

Working principle of BFC237515222:it utilizes the electrostatic capacitor principle and consists of metalized polyester film as dielectric medium, with two metalized plastic film electrodes fixed on it. When an AC voltage is applied to the terminal, a dielectric platform will generate on the surface of the metalized film layer. At this time, depending on the frequency, the capacitor acts as an inductor. After that, a dielectric platform is generated on the nonmetalized plastic film, and the capacitive effect occurs in the capacitor.

In conclusion, BFC237515222 is a film capacitor and it is widely used in electronic and electrical appliances. It works by utilizing the electrostatic capacitor principle and consists of metalized polyester film as the dielectric medium, with two metalized plastic film electrodes fixed on it. It is designed with high-grade materials, providing outstanding properties, such as good insulation, long service life and low temperature drift.
