Film Capacitors

Film capacitors are a type of capacitor which use a dielectric film of plastic, mica, ceramics, paper and other materials to store electrical charge. In particular, BFC233913273 film capacitors are known for their noise suppression and superior stability in high temperature applications. Through their use of a wide range of materials, film capacitors are also able to withstand pressure and current spikes.

Application Field of BFC233913273 Film Capacitors

One of the most important features of BFC233913273 film capacitors is their wide range of applications. In particular, they are ideal for high frequency switch mode power supplies. Due to their noise suppression qualities, BFC233913273 capacitors are also being used in digital audio sound systems. Other applications include pulse circuits, LCDs, VCRs, and more general electronic circuits.

Working Principle of BFC233913273 Film Capacitors

At the most basic level, film capacitors consist of two conductors separated by a dielectric medium. This dielectric medium can be any of a number of materials, but most frequently it is made from a film of plastic. When a voltage is applied between the two conductors, an electric field is created and electrons are attracted to the surface of the conductor closer to the voltage source. This phenomenon creates a charge across both of the conductors, referred to as the capacitance.

When the applied voltage is removed, the charges on the two conductors remain in place, creating a storage of energy. Once the capacitance reaches a maximum amount, the film capacitor is said to be fully charged and the voltage can no longer traverse through it. This process is what makes a capacitor useful in a variety of electrical applications.

The stability of the dielectric is what makes BFC233913273 film capacitors so well suited for certain applications. As mentioned above, the plastic can withstand pressure and current spikes, meaning that the capacitance remains consistent regardless of the amount of current running through the device. This stability makes BFC233913273 film capacitors superior in high temperature applications.
