Film capacitors are electronic components that form their core by connecting a dielectric film and two electrodes of opposite polarity. BFC2373FF394MF is a film capacitor of this type. In this article, the application field and working principle of this type of capacitor will be elaborated in detail, so that readers can gain a better understanding of the device.

Application Field

BFC2373FF394MF film capacitor can mainly be used in a wide range of fields, such as power electronics, precision medical and telecommunication equipment, AC systems, industrial motors, automotive electronics, etc. It serves as an important part of AC power filter, voltage regulator, power measurement system, and surge protection. It can provide various degrees of protection to the circuits being used, ensuring reliable and stable operation of the circuit when working with AC and DC currents.

Working Principle

The BFC2373FF394MF film capacitor consists of two metallic electrodes, each one either connected to the terminals of the capacitor or applied to the other side of the substrate of the film. When these electrodes come into contact with AC or DC current, a certain potential difference appears between them. This then sets up an electric field between the two electrodes and the film, which generates dielectric polarization. As a result, dielectric absorption and displacement parameters of the film are improved, leading to the establishment of an area of increased capacitance.

However, when dealing with AC current, the electric field between the electrodes and the dielectric film reverses its direction with the change of the current\'s polarity. This generates a phenomenon called the dielectric polarization reversal. Consequently, the capacitor\'s capacitance value will be affected by this change. This is precisely the process of how a film capacitor works when exposed to different currents, depending on the orientation and polarity of the electrodes.

Conclusion

In conclusion, the BFC2373FF394MF film capacitor is one of the most popular capacitors on the market, thanks to its wide application field and its reliable working principles. It is easy to install and use for many types of circuits. Furthermore, its dielectric absorption and displacement parameters can be quickly improved to offer reliable and stable protection in AC and DC systems.
