Film Capacitors

A Film Capacitor, also known as a Plastic Film Capacitor, Polyester Film Capacitor, or PFC, is one of the most versatile capacitors. They are widely used in large range of applications, ranging from communication systems, consumer electronics, automotive, aerospace, energy and industrial control systems. The BFC2370EI393 is a popular Film Capacitor used in a variety of applications.

BFC2370EI393 Application Field

The BFC2370EI393 is an aluminum electrolytic capacitors, a type of plastic film capacitor, rated for 200 Vdc. It is a very reliable and cost effective capacitor for a variety of applications. It is especially suitable for power supply applications and motor control. It can also be used in other applications such as pulse motor, hot-wire detection, power supply switching circuits and timer circuits.

Working Principle

The working principle of a Film Capacitor is quite simple. A thin sheet of polyester, polypropylene, or other plastic film is sandwiched between two conducting plates. The plates formed the two electrodes of the capacitor. When a charge is applied to the electrodes, the electric field created will cause the two plates to attract each other. This creates an electrical connection that stores energy.

As the voltage applied to the capacitor increases, the plates will closer and thereby storing more energy. Because of this, capacitors like the BFC2370EI393 are able to store and discharge energy quickly. This makes them suitable for high speed applications and power supplies.

Conclusion

The BFC2370EI393 is a popular and cost effective plastic film capacitor. It is rated for 200 Vdc and is suitable for a range of applications such as power supply, motor control, pulse motor, hot-wire detection and timer circuits. The working principle of a Film Capacitor is thus based on the electric field created on two metallic plates due to an applied charge.
