Film capacitors, also known as plastic film capacitors, polyester capacitors or polyethylene terephthalate (P.E.T.) capacitors, are electrical capacitors that contain a thin layer of plastic film as the dielectric material. The B32022B3223K289 is an example of a film capacitor, and its application and working principle are briefly outlined below.

Application

The B32022B3223K289 is designed for applications that require high-frequency stability, low ESR, and high-temperature operation. Its features make it well-suited for use in automotive, audio, power supplies, and HVAC applications. Its small size and light weight make it easy to integrate in existing circuitry, while its non-polar design makes it less susceptible to heat and moisture. Additionally, the B32022B3223K289 is RoHS compliant. As a result, it is an excellent choice for applications where safety, reliability, and energy efficiency matter.

Working Principle

The B32022B3223K289 consists of two metalic electrodes that act as the positive and negative plates of the capacitor. In between these two plates is the dielectric material, two layers of polyethylene terephthalate (P.E.T.), which provides good insulation properties. This film is then protected by a layer of metalized film that acts as the outer shielding. In this configuration, electrical power is generated when an external voltage is applied. The electrical charge is stored on the dielectric material, which prevents current from flowing and produces a capacitive effect.

The B32022B3223K289 works by storing the electric charge, similar to a battery. However, unlike a battery, the capacitor does not have a steady stream of current and is not bound by charging and discharging cycles. Instead, the voltage is applied to the capacitor for a short period of time, and then the capacitor is left to discharge and reset itself. This makes it ideal for applications that require high-frequency stability, low ESR, and high-temperature operation.

Conclusion

The B32022B3223K289 is a high-performance film capacitor, designed for applications that require superior stability and performance. Its small size and light weight make it easy to integrate into existing circuitry, while its non-polar design makes it less susceptible to heat and moisture. Additionally, it is RoHS compliant, making it an excellent choice for applications that require reliability and energy efficiency.
