Film capacitors refer to capacitors that use plastic films as the dielectric. They are formed by two layers of metal deposition on the film, and their main application fields are relatively wide. Among them, BFC238041363 series is the most common and widely used film capacitor in today\'s electronic industry. In this article, we will discuss its application field and working principle.

Application Field of BFC238041363

The BFC238041363 series is mainly used in low frequency rectification, power frequency rectification, intermediate frequency rectification, DC line filter power supply, DC-DC converter, power supply switch and other electronic equipment, as well as radio, communications, radar, missile navigation and other high-frequency equipment.

Due to their good insulating performance, small volume, light weight, wide frequency response, low loss, strong anti-interference ability and other characteristics, they can effectively reduce / filter the ripple voltage of the signal, and stabilize the power supply voltage, improve the operating efficiency of the equipment, reduce the external environment interference and other effects, and improve the accuracy of the equipment. Therefore, they are widely used in the above electronic equipment.

Working Principle of BFC238041363

BFC238041363 capacitors belong to the category of film capacitors, which are formed by two layers of metal depositing on the plastic film. Under the action of the electric field, charge accumulates on the two metal layers, and the oxide layer of the plastic film becomes the dielectric of the capacitor. The insulating film used in the BFC238041363 capacitors is made from a composite of PET, PP and Cotton paper, so it has excellent high-temperature tolerance, low leakage current, and a wide range of temperature stability.

In the circuit, the current of the capacitor can be continuously charged and discharged, but the instantaneous current should be controlled within a certain range. Generally, capacitors with a certain capacitance should be selected to meet the application requirements in various power electronic devices. During the charging and discharging process, due to the accumulation and dispersion of charges on the two surfaces of the capacitor, there is an electric field between the two. If the charging voltage increases, the electric field will gradually increase until the breakdown voltage, at which point the capacitor will be damaged.

Conclusion

In conclusion, the BFC238041363 series film capacitors are widely used in a variety of electronic equipment, from low frequency rectification, power frequency rectification, intermediate frequency rectification, to DC line filter power supply, DC-DC converter, power supply switch and more. They have excellent insulating performance, small volume, light weight, wide frequency response, low loss, and strong anti-interference ability. This makes them highly reliable in the electronic industry.
