Film capacitors are a type of capacitor commonly used today. These capacitors are particularly useful in high frequency, high current applications, where their durable construction and ability to pass large current through them make them ideal. The BFC238035473 is one such example of a film capacitor, and in this article we’ll be taking a look at its application field and working principle.

BFC238035473 Application Field

The BFC238035473 film capacitor is designed for use in high frequency, high current applications, where its ability to handle large current loads makes it an ideal candidate. It’s particularly suited for applications such as high frequency switching power supplies, power amplifiers, radio frequency filters, and voltage multiplier circuits. The film capacitor is also a popular choice for use in high voltage AC circuits where its resilience to dielectric absorption is very useful.

BFC238035473 Working Principle

The BFC238035473 film capacitor consists of two metal plates separated by a thin layer of plastic film. The plates are coated with an electrode material, such as tin or nickel, which allows electrical current to pass through them. The plastic film acts as an insulator, preventing the two plates from coming into direct contact with each other. As a result, when a voltage is applied across the two plates a capacitance is created, which stores electrical energy.

The amount of capacitance created by the BFC238035473 film capacitor is determined by the amount of area of the two plates, the distance between the plates, as well as the type of film used. The film is typically made of polypropylene, although other materials, such as polystyrene, may also be used. The thickness of the film is also important, as the thicker the film the higher the capacitance.

The BFC238035473 film capacitor is especially useful in high voltage applications due to its resilience to dielectric absorption. This is a phenomenon in which the capacitance of the film capacitor will increase over time due to the gradual accumulation of charge on the capacitor’s plates. In high voltage applications, this can result in a number of issues including voltage spikes and excessive heating. By using a film capacitor that is less prone to dielectric absorption, these issues can be avoided.

Conclusion

The BFC238035473 film capacitor is a popular choice for use in high frequency, high current applications. Its ability to handle large current loads and its resilience to dielectric absorption make it an ideal candidate for any circuit, especially high voltage circuits.
