Additionally, it is applied in various household appliances, such as TVs, air conditioners, refrigerators, microwave ovens, new energy vehicles, and other high-end electronic products.

Working Principle

The working principle of BFC2373FL124MD consists of a mica film dielectric medium, aluminum foil, epoxy resin, aluminum cathode and anode protection. By the combination of these materials, a very low Q tangent loss can be realized, which contributes to the capacitor’s stability and reliability. The mica film dielectric medium is in the form of plates, and the dielectric constant between them creates an electric field. When the electric field changes, voltage charges will move through the capacitor’s plates and charging will occur, leading to the build-up of voltage.

The electric field is also intensified when a voltage is applied to the capacitor. The capacitance of the film capacitor is determined by the area of the plates and their distance from each other. This affects the electric field that exists between them and determines the amount of voltage that can be stored in the capacitor. When the voltage changes, the electric field also changes, leading to flow of current.

Conclusion

In summary, BFC2373FL124MD is a special type of film capacitor with a rated voltage of 250VDC and wide temperature tolerance. It is mainly used in power supply circuits, LCDs, and various signal switch circuits for power filtering, smoothing, signal mixing, signal amplification, and DC compensation of various analog circuits. Its working principle consists of a mica film dielectric medium, aluminum foil, epoxy resin, aluminum cathode and anode protection. The capacitance of it is determined by the area of the plates and their distance from each other. It is suitable for many applications due to its stability and capacitance range.
