Film Capacitors

The BFC238321913 is a film capacitor that can be used in a variety of electronic applications. This type of capacitor is made up of a thin, dielectric polyester film, rolled up with epoxy resin-soaked layers of aluminum foil. The combination of materials gives it high tolerance to humidity and heat, which make it an ideal component for use in electrical and electronic equipment with sensitive surfaces.

In terms of its application fields, film capacitors are extensively used in power supplies, electronic filters, audio crossovers, and other circuits where small amounts of noise and waves need to be attenuated. It is also used in high-stability requirements that require a stable capacitance value in the long-term.

As for the working principle, the production of a film capacitor begins with the dielectric material which is composed of thin layers of polyester. When a voltage is applied, the electric field lines align within these layers, generating an electric charge that becomes stored in the capacitor. The material then acts as an insulator, creating a stratum allowing the capacitor to store the charge. In turn, this stored charge generates an opposite electric field in the opposite direction of the voltage applied. When the voltage is removed, the stored charge inside the capacitor is removed and it can no longer store a charge.

The great advantage of this type of capacitor is that its small power consumption makes it suitable for circuit control applications such as frequency control or pulse control. Furthermore, it has improved noise suppression in comparison to other types of capacitors, and combines a high capacitance value with a long life in high temperature environments.

In conclusion, the BFC238321913 is a film capacitor that offers a great solution for applications involving low power consumption and high stability, where noise needs to be efficiently reduced.
