Film Capacitors

The BFC237155392 is a type of film capacitor which is a component used in electronic circuits. It is a member of the family of thin film capacitors which have a dielectric layer of polyimide film treated with aluminum oxide which is typically oil, vacuum, or air impregnated. Film capacitors are typically used in low-voltage DC and AC circuit applications, such as signal and power conditioning, across-the-line protection, and as energy storage elements.

BFC237155392 Application Fields

Film capacitors are used in a variety of applications, including power-line protection, decoupling, pulse-width-modulated (PWM) circuits, and AC power-line filters. They are also used in AC mains-line surge suppression, computer-controlled and other consumer electronics devices, and test and measurement equipment. The BFC237155392 is a medium-voltage film capacitor with leaded terminals, and is well-suited for use in these applications.

BFC237155392 Working Principles

The BFC237155392 is a voltage-doubling film capacitor. It doubles the voltage of AC voltage sources, and can be used to bridge the gap between levels of AC power, creating a separate and uninterrupted voltage path. The capacitor contains two asymmetric capacitors connected in series and is used mainly for decoupling high-powered circuits, but can also be used for partially blocking high frequency noise. The leads of the capacitor are connected to AC voltage sources, which cause the capacitors to respond to the frequency of the voltage source.

The capacitor works by using the charges on the two supporting metallic plates to store electrical energy as the two metallic plates are charged up with opposite charges. As a result, a voltage is created across the two plates, which is higher than the AC voltage source. Increasing the number of capacitors can increase the voltage of the AC voltage source, which can be used to bridge the gap between levels of AC power.

Conclusion

The BFC237155392 is a medium-voltage film capacitor with leaded terminals and is well-suited for use in power-line protection, decoupling, PWM circuits, AC power-line filters, and other applications. Its working principle is based on the use of two asymmetric capacitors connected in series to double the voltage of AC voltage sources, and create a separate and uninterrupted voltage path. With its high-reliability and low-impedance performance, this capacitor is an effective choice for many applications.
