Film Capacitors

A film capacitor, also known as a plastic film capacitor, is a type of capacitor that is constructed from thin plastic film as the dielectric instead of the more traditional paper. Its advantages include lower capacitance loss, larger capacitance values, and increased surge current capability.

BFC2370GF472 application field and working principle

The BFC2370GF472 film capacitor is designed for AC and pulse electrical circuits, and it\'s mainly used in high frequency switching power supply circuits, LCD display circuits and printers. It is also widely used in AC motor starting, phase shifting, speed control and other circuits. This film capacitor has a capacitor group with a high ripple current capacity, low dielectric loss, low temperature coefficient and high insulation resistance.

The BFC2370GF472 film capacitor functions by storing electrical energy in its metalized film, which acts like an insulating layer between two conductive metal plates. When a potential difference is applied between the two plates, the metalized film stores electricity in the form of an electric field. The capacitance of the capacitor is determined by the area of the plates and the distance between them, which is also known as the thickness of the dielectric.
