BFC2370GH202 application field and working principle
Film capacitors are extremely reliable, low-loss components specially designed for applications such as decoupling, suppression and filtering. BFC2370GH202 film capacitors are particularly well suited for applications requiring high capacitance values and low loss. Construction
The BFC2370GH202 is a polypropylene dielectric film capacitor with a metalized polypropylene dielectric. It has a compact, lightweight construction and is available in a wide range of voltages, capacitance values and tolerances. The conductive metalized polypropylene dielectric provides excellent stability and very low ESR. A wide range of terminations are available, including metal, flexible and rigid connecters, as well as portable, waterproof, IP66 and vandal-proof versions.

Working principle

Film capacitors are non-polarized which means that they can be connected in either direction without fear of damage to the capacitor or circuit. The working principle of the BFC2370GH202 is based on the principles of capacitance. It consists of two metalized layers of plastic separated by an insulating layer of dielectric material. When an electric field is applied across the two plates, a charge is stored in the dielectric medium. The amount of charge stored is proportional to the amount of voltage applied. The dielectric material of the capacitor specifies the amount of charge that can be stored and therefore the capacitance.

Applications

BFC2370GH202 film capacitors are widely used in a variety of applications. Some of the more common applications include power supplies, DC blocking, noise suppression and filtering, EMI/RFI suppression, timing and frequency control. BFC2370GH202 capacitors are also widely used in loudspeaker crossovers, high-end audio equipment, automotive audio, automotive ignition systems and battery backup systems. They are also used for specialty applications such as position transducers, antenna couplers and military systems. The low ESR and high capacitance values make them ideal for a variety of high frequency applications as well as for a variety of noise filter and voltage regulator designs.
