Film capacitors are one type of ceramic capacitors that possess the characteristic of being lightweight and having a superior breakdown field strength. BFC233914335 film capacitors belong to this type of capacitors whose application field and working principle are discussed in this article.

Basics of Film Capacitors

Film capacitors are composed of dielectric films that are divided into two layers: inner and outer. Each layer is put between two metal electrodes, with the inner ones forming the element electrodes, while the outer ones taking the function of connecting the film capacitors into the circuits. Compared to the other types of ceramic capacitors, film capacitors are superior in terms of their dielectric constant and their Withstood peak voltage, where the former is determined by the thickness of the dielectric films, and the latter can reach up to 40kVAC.

Working Principle of BFC233914335

BFC233914335 film capacitors are designed with a double-layer structure, consisting of two metalized PET or PP film, and a PA 66 stitching. Each metalized paper contains a PTFE along with other insulation materials, to ensure the good long-term stability as well as the high temperature resistance. In such capacitors, the metalized films are divided into a series of small squares, with each area connected by the PA 66. In the operation, electrons pass through one metalized film to another, thus creating a capacitor.

Applications of BFC233914335

BFC233914335 film capacitors are extensively used in many applications. Typical scenarios include impedance matching, resonant circuits and AC peak absorbing. In particular, thanks to its excellent Withstood peak voltage, such capacitors can perform especially well in cases with high-frequency and high-voltage pulses. Thus, it is widely applied in high power amplifiers and professional audio equipment, to ensure the stability of operation and reduce the noise.

Conclusion

This article discusses the application field and working principle of BFC233914335 film capacitors. Such capacitors are composed of two metalized films and an insulation material, with their Withstood peak voltage rate reaching up to 40kVAC. They are often used in impedance matching, resonant circuits and AC peak absorbing, and are especially suitable for high power amplifiers and professional audio equipment due to their high Withstood peak voltage.
