Film Capacitors

The BFC237542511 series of film capacitors provide a variety of electrical and mechanical properties. They are used in a wide variety of applications, including power factor correction, motor control, audio/video, and medical applications. The capacitor itself is composed of two pieces of metallized film, which are separated by a small air gap. The metallized film is then thermally bonded to the outside of the capacitor, forming the dielectric.

Application Field

Film capacitors are often used in contexts where a capacitor’s size, stability, and performance are necessary. As the BFC237542511 series have a very high capacitance, it is preferred for applications where a large amount of energy must be stored and discharged quickly. This can include applications such as motor control, power factor correction, and audio/video. Furthermore, because of the high reliability and long life of film capacitors, they can also be used in medical and aerospace applications.

Working Principle

Film capacitors typically work on the principle of electrostatic field. When a voltage is applied to the terminals, it causes a charge to build up on the dielectric separating one terminal from the other. This charge is then stored in the capacitor, allowing it to hold a steady polarity or voltage. When current is discharged, the electrons will flow from the negative terminal to the positive terminal, and the capacitor will be fully discharged.

Conclusion

The BFC237542511 series of film capacitors provide a wide range of electrical and mechanical properties, making them suitable for a variety of applications. Their high capacitance and reliability make them suitable for motor control, power factor correction, audio/video, and medical applications. As the dielectric of these capacitors is made up of two pieces of metallized film which are separated by a small air gap, their working principle is based on the electrostatic field.
