Film Capacitors

Film capacitors are non-polarized, dielectric capacitors that are composed of a plastic film dielectric, in which two aluminum electrode layers are laminated. Typically the plastic film has a thickness of 0.2 to 0.5 micrometers, and ranges in size from a few millimeters in diameter to several centimeters in length. Film capacitors are generally used in applications where their low leakage current, low dielectric absorption, and high insulation resistance are important.

B32621A0222J000 Application Field

The B32621A0222J000 is a low-voltage film capacitor designed for high-frequency circuits and is capable of withstanding up to 4,900 volts. This capacitor is well-suited for use in motor controls, precision electronics, switching power supplies, and signal transmission and buffering. It is used for general DC-blocking, signal coupling, off-state filtering, and power line noise suppression applications.

B32621A0222J000 Working Principle

The B32621A0222J000 is a non-polarized capacitor meaning that it does not have a positive and negative terminal. Its working principle is based on the dielectric capacitor, also known as an insulator. The dielectric material of the capacitor is the plastic film that is sandwiched between two layers of aluminum foil electrodes. When a voltage is applied to the capacitor, an electric field is created across the dielectric material which causes a displacement current to flow. This displacement current causes the capacitor to store a charge of electrical energy.When the voltage is removed from the capacitor, the stored energy is slowly discharged through its internal leakage current, also known as its “ESR” (equivalent series resistance). The B32621A0222J000 operates in the range of 0–100 kHz and provides excellent noise immunity, high insulation resistance and high ripple current capability.

Conclusion

The B32621A0222J000 is a low voltage film capacitor ideal for high-frequency circuits. It is used in motor control, precision electronics, switching power supplies, signal transmission and buffering applications. Its working principle is based on the dielectric capacitor which works by creating an electric field across the dielectric material creating a displacement current which causes it to store electrical energy. The B32621A0222J000 operates in the range of 0–100 kHz and provides excellent noise immunity, high insulation resistance and high ripple current capability.
