Introduction

Film capacitors, also known as plastic film capacitors, are capacitors that use plastic films as electrodes with high breakdown voltage, increased stability, high safety, and long lifetime. Due to their low loss and excellent stability, film capacitors are widely used in the electronics industry. Among them, FCP0805H221J-J1 stands out from others as a great alternative for capacitors. In this article, we will discuss the application fields and working principle of FCP0805H221J-J1 film capacitor.

Application Field

FCP0805H221J-J1 is a large capacity film capacitor, with higher capacity and wider temperature differences. It is mainly used in electrical engineering, power supplies, power factor compensation, high voltage circuits, radio frequency inverters, electronic switches and ballasts, high voltage rectifiers, decoupling and damping circuits, among others.FCP0805H221J-J1 film capacitors are also applied in three-phase AC ripple voltage suppression, used in AC circuits to reduce output ripple voltage. It can effectively limit the amplitude of the AC ripple current, reduce AC resonance and increase the accuracy of the AC ripple rectifying circuit. Therefore, the FCP0805H221J-J1 capacitors are widely used in AC ripple rectifying circuits.

Working Principle

The FCP0805H221J-J1 film capacitor is made up of two metal plates separated by a thin dielectric material. The metal plates act as electrodes and the dielectric material acts as an insulator. When a voltage is applied across the two electrodes, an electric field builds up between them, and the dielectric ensures that almost all of the energy is stored in the gap between them. This energy is referred to as electrostatic energy and forms part of the capacitor’s working principle.When the voltage is increased significantly, at a certain point, the electric field becomes so strong that it overwhelms the dielectric and current leaking from the capacitor’s metal plates begins to flow. This sets off a chain reaction of further current leakage, known as the breakdown of the capacitor, which damages the device.

Conclusion

The FCP0805H221J-J1 film capacitor is widely used in electrical engineering, power supplies, power factor compensation, high voltage rectifiers, decoupling and damping circuits, three-phase AC ripple voltage suppression, among other applications. This capacitor utilizes the electrostatic energy stored in the gap between two electrodes as its working principle, and is able to store energy until a certain point, when the electric field overcomes the dielectric and current begins to flow, leading to the breakdown of the device.
