Film Capacitors

Film capacitors, also known as plastic film capacitors, are capacitors whose dielectric is a dielectric film. This name can also include mica and ceramic capacitors. These capacitors are generally characterized by very stable capacitance and loss values, as well as high insulation resistance and good temperature properties. They can also be a low-cost solution for a wide range of applications.

The BFC237676393 is a film capacitor from Vishay that is designed for use in a variety of AC operations. It features a very low ESR down to 1.3 milliohms and a very high self-healing rate. This makes it suitable for a range of AC operations such as power factor correction (PFC) and AC motor filtering, as well as LED lighting and rectification.

Application Field of BFC237676393

The BFC237676393 is capable of using high frequencies up to 2 kHz. This makes it ideal for PFC and AC motor filtering applications because it provides low parasitic drops and can be used to improve the performance of the system. Additionally, it can act as a low-cost solution for LED lighting and rectification applications by providing low parasitic elements and high self-healing rates.

The BFC237676393 is a great choice for high-current applications because of its high current ratings and low ESR. Additionally, its low inductance makes it well-suited for use in higher-frequency applications. It is also a good choice for EV and automotive applications because of its low weight and high temperature ratings.

Working Principle of BFC237676393

A film capacitor consists of two metal plates, separated by a dielectric film. This film acts as a dielectric between the two plates, and when a voltage is applied, charges are stored on each plate. The amount of charge stored on the plates is determined by the capacitance of the capacitor. This capacitance is then used to store and regulate electrical energy.

In the case of BFC237676393, the film dielectric is a polypropylene film. This type of film has high dielectric strength and can maintain a very low level of distortion when exposed to high-frequency operation. Additionally, polypropylene dielectric films also have a very low level of dielectric losses when in use.

The BFC237676393 also has a self-healing feature. The self-healing effect is caused by the dielectric film. When a high voltage is applied, the dielectric film will break down, removing any electric charge that may be stored. The break down of the film will produce heat that will cause the film to reform, resulting in a decrease in capacitance. This self-healing effect will help to ensure a constant capacitance throughout the life of the capacitor.

Conclusion

The BFC237676393 is a film capacitor from Vishay that is designed specifically for AC operations. It has a very low ESR down to 1.3 milliohms and is well-suited for a range of AC operations. It is also well-suited for applications that require low parasitic elements. The self-healing effect of the film capacitor helps to ensure a constant capacitance throughout its life.
