Capacitor is a two-terminal, passive electrical storage device which plays an important role in electrical industry. Film capacitor can be divided to many types, and B32673P6684K000 is one of the film capacitors. This article will discuss the application field and working principle of B32673P6684K000 film capacitors.

Application field

B32673P6684K000 film capacitors are a kind of popular capacitors, especially in switching power supply, UPS, motor drive. It can be applied to filter and reduce the noise, especially in the frequency of harmonics, so electric products can be ensured with a reliable power supply.

B32673P6684K000 film capacitors also can be used in other fields. They are often used in amplifier circuit, particularly in high fidelity circuit and can play a role in energy storage, current limitation and frequency selection. In addition, B32673P6684K000 capacitors can be used in EFI system, emergency power system, power amplifier, fan regulators, etc.

Working principle

In the basic structure of a film capacitor, perhaps the most important part is the dielectric. The dielectric layer is usually polyester, polycarbonate or paper. It divides the capacitor into two parts with opposite electrical poles. When an electrical charge is applied, one part will accept electrical charge while the other will give it up, creating an electric field.

The electric field can induce a current in the conductor and within the semiconductor. The dielectric material of a film capacitor can control the magnitude of the electric field, and therefore, the amount of charge that can be stored in the capacitor. The dielectric material also affects the ability of the capacitor to hold charge over time. Generally, capacitors with higher dielectric constants, such as polycarbonate and paper, will hold charge more effectively than those with lower dielectric constants.

The working principle of B32673P6684K000 film capacitors is based on the same principles as all other kinds of film capacitors, where metal plates are separated by a thin insulating layer, usually polyethylene. When an electric charge is applied to the plate, the electric field established between them attracts negative ions, forming a conductive layer, producing an electrical current through the capacitor. The film capacitor can hold the charge for quite a long time and its ability to store and release charge is also quite fast.

In conclusion, B32673P6684K000 film capacitors are widely used in power supply, UPS, amplifier circuit, EFI system, emergency power system, power amplifier and fan regulators. Working principle of these capacitors is also quite simple, the electric field established between the plates attracts negative ions, forming a conductive layer, producing an electric current through the capacitor. Their ability to store and release charge is also quite fast.
