Film capacitors are electronic components designed to store energy. They are often used to provide energy storage, reduce distortion, and act as filters in circuits. B32652A2221J189 film capacitors are a customized series, designed and developed on the basis of B32652 film capacitors from TDK.

Application Field

The application field of B32652A2221J189 film capacitors mainly includes power supply, high frequency circuits, audio and broadcasting circuits, automotive electronics, and electronic ballast. It can be used in communication systems, digital signal processors, low and medium voltage frequency converters, chargers, variable speed drives, and other application areas.

Working Principle

Film capacitors are built using a wide variety of electrical insulating materials. These are sandwiched between two electrodes that act as plate electrodes. The working principle of these capacitors is based on the electrostatic attraction-repulsion of particles in an electrical field between the two electrodes. Every time a voltage is applied to these electrodes, the particles become positively or negatively charged, which causes the charge to be stored in the dielectric layer.

Advantages
