Film Capacitors

A film capacitor, or plastic film capacitor, is a type of capacitor that uses film as the dielectric, and therefore has electrical characteristics that are different from those of ceramic capacitors and electrolytic capacitors. One of the most commonly used film capacitors is the BFC237874113.

Application Fields

Film Capacitors like the BFC237874113 are used in a variety of applications, such as filtering, buffering, and pulse shaping, to name a few. It is ideal for impulses sparking, micro-residential motors, industrial controllers, consumer electronics, amplifiers, and personal computers. These capacitors are often used in switching power supplies as well, due to their ability to quickly store and release energy.

Working Principle

The working principle of a film capacitor is the same as that of other types of capacitors. An electric field is created by a voltage applied across the plates of the capacitor, which causes a current to flow. This current creates an electric field within the plates and a resultant electric field outside the plates. The dielectric material of a film capacitor is usually a polyester, polypropylene, polycarbonate, or polystyrene film, and the plates are bonded to the film. The film can be impregnated with oil, which assists in reducing the electrical losses. The dielectric film is punctured with holes to allow for the passage of electric current. When the voltage is applied, the electric field produced near the capacitor’s plates causes the current to flow through the film, thereby creating an electrical charge in the plates. This stored charge will remain until the capacitor is discharged.

Conclusion

The BFC237874113 is an excellent example of a film capacitor, and is used in a wide variety of applications. Its working principle is similar to that of other types of capacitors, and its dielectric material is composed of various materials that allow for the passage of electric charge. This makes it an ideal choice for use in switching power supplies, as well as in other electronic and electrical applications.
