Working Principle

The BFC237673472 is a plastic film capacitor with a bi-polar structure. It has two metal foil electrodes separated by a dielectric plastic film. The metal foil electrodes, terminal leads, and mounting brackets are all made of aluminum, which is not affected by oxidation. The dielectric plastic film is non-toxic and insulated.

The working principle of the BFC237673472 is simple. When the capacitor is connected to an AC power supply, the electric field in the capacitor causes electrons to be attracted to the negative terminal and repelled from the positive terminal. The electrons move repeatedly between the terminals, and this process of charge flow creates an electric field in the capacitor. This electric field then filters the AC ripples, providing steady voltage.

In addition, the BFC237673472 also has a high dielectric constant that allows for a higher capacitance than other Film Capacitors. This higher capacitance helps to increase the filtering effect of the capacitor, making it suitable for low-power applications.

Conclusion

The BFC237673472 is a plastic film capacitor that is widely used in AC motor start-up/motor run applications, lighting fixtures, LED luminaires, LED displays, power controllers, and circuit protection. It has high current capability, low ESR, long life, and high reliability. Its working principle is based on creating an electric field that filters the AC ripples and provides steady voltage.

In conclusion, the BFC237673472 is a reliable and efficient film capacitor for a wide range of applications. It is an ideal choice for applications where the highest reliability and performance are required.
