BFC236751822

Film capacitors, also known as plastic film capacitors, are electronic components widely used in a variety of applications. The BFC236751822 is a film capacitor specifically designed for high-frequency switching power supplies. In this article, we will describe its principal application area and operating principle.

Application field of the BFC236751822

The BFC236751822 is a film capacitor specifically designed for high-frequency switching power supplies. Such applications may include electronic devices such as televisions, computers, mobile phones, and household appliances. It is used as an AC filter which filters out noise and reduces switching power conversion loss, thereby maintaining a steady voltage for the device. In addition, the BFC236751822 is also suitable for high voltage pulse applications, such as voltage discharge, X-ray machine, energy storage circuit. Since its rated working temperature can reach 125°C, it can also be used in occasions with higher working temperature.

Working Principle of the BFC236751822

The BFC236751822 film capacitor stores electrical charge in its dielectric insulation film. It has an anode film and a cathode film as its two electrodes, and the capacitance is determined by the size of the interlayer distance. The surface of the anode and the cathode film is specially treated to ensure the film capacitor has a high electric stability and a long life span. When a AC voltage is applied, an alternating electric field is generated between the two layers. The electronic charges flow to both sides of the film alternately, leading to a change in the magnitude and direction of the electric field. This explains why an AC signal can pass through a capacitor, but a direct current will be blocked.

In short, the BFC236751822 film capacitor is specifically designed for high-frequency switching power supplies. Its rated working temperature can reach 125°C, making it suitable for pulse applications and strong electric field environments. Thanks to its specially treated anode and cathode films, the BFC236751822 capacitors have superior electric stability and long life span.
