BFC238330163

Film capacitors, also known as dielectric film capacitors, are mainly made of insulating material such as film, paper and ceramic. BFC238330163 is a film capacitor characterized by high rated voltage and large capacity. This article discusses the application field and working principle of the BFC238330163 capacitor.

Application field

BFC238330163 film capacitors are widely used in chemical, electronic and electrical industries. For example, it can be used as signal coupling, bypassing, decoupling, blocking, snubber, and energy storage in various electronic devices. Also, it can be used in high voltage circuits, such as voltage division and compensation, and can be used as a power supply filter and anti-interference effect. In addition, its capacitance and dissipated energy can be adjusted by adjusting the size of the capacitor and changing the medium between the plates.

Working principle

The working principle of BFC238330163 film capacitor is mainly related to its internal structure. The BFC238330163 capacitor consists of two metal plates, which are separated by an insulating material. When a voltage is applied to the plates, a capacitance will be generated between them due to the accumulation of electric charge. Thus, when a current passes through the capacitor, the electric charge accumulated on the plates will be discharged, allowing current to flow. However, when the voltage is removed, the electric charge will no longer be generated, thus no current will be discharged.

In addition, the BFC238330163 capacitor has a self-healing structure. When over-voltage or short circuit occur, the capacitance of the capacitor can effectively protect the system by self-healing. The self-healing process can be explained as follows. First, when the current is excessive or short-circuit, impacting the dielectric between the plates, the dielectric will suffer partial breakdown. The conductive material formed by the breakdown conducts electricity, but the current is very low. Thus, the current will no longer cause permanent damage. This self-healing cycle will be repeated until the breakdown is completely eliminated.

Conclusion

In conclusion, BFC238330163 film capacitors are widely used in chemical, electronic and electrical industries due to their high rated voltage and large capacity. Its working principle is mainly related to the internal structure of the capacitor, including two metal plates and an insulating material. In addition, it also has a self-healing structure, which can effectively protect the system by automatically eliminating over-voltage or short circuit.
