Application Field

Film capacitors are widely used in all kinds of electronic circuits due to the advantages of high insulation stability, wide operating temperature range, satisfactory stand-by capacity and dimensional accuracy. The BFC237169393 is normally used in AC and DC smoothing circuits, DC blocking circuits, sample and hold circuits, pulse start and protection circuits, energy conservation circuits, frequency divider circuits, blocking circuit of low voltage DC power supply. In addition, because of its good self-healing properties, the BFC237169393 film capacitor is also used in high voltage power stage circuits and surge withstanding circuits.

Working Principle

The operation of the film capacitor relies on the law of capacitance. When one end of the film capacitor is connected to a higher potential than the other end, it will cause the potential on the plates to increase. This will push the electrons in the plates to positive side, while pulling the electrons on the negative plates to oppose the current. This action will create an electrical field between the two conducting plates, which is called "capacitance". This principle of capacitance is the foundation of its operation.

Therefore, the BFC237169393 film capacitor is ideal for a variety of applications due to its properties like high stability, low noise, excellent capacitance, high reliability, and good surge withstanding capability.
