It is often used to filter signals of low frequency, and low noise. In addition, BFC238341433 film capacitors can work effectively in the most rigorous mechanical and electrical environments which require its dielectric film remain strong and reliable over an extended time.

Working Principle

BFC238341433 film capacitors use a plastic film as the insulator between two metal plates. By using a dielectric film such as polyester, polypropylene, paper or Teflon, the capacitance of the film capacitor can be managed. The construction is simple which consists of metalized film, connected with both terminals. Besides, the capacitance of the film capacitor is mainly determined by the area of the plates, the distance between them and the dielectric constant of the plastic film that separate them. When operate, the dielectric film creates an electric dipole field between the two metal plates. When a voltage is applied, the polarization charge of the dipoles opposes the rate of the change and the field strength will be increased.
