Film capacitors are widely used as components in circuits for power supply, actuating and control equipment, consumer electronics, and telecommunications. The B32620J0222J189 capacitor is one of the most popular types of film capacitors. Its application fields are diverse and its working principle is simple.

The B32620J0222J189 capacitors are designed to be used in a wide range of applications. These include motor run and driver-overload protection, power factor correction, automotive system protection and energy storage, overvoltage protection, node snubbing, ripple current control, measurement and test equipment, air conditioning systems, and many more. It is well suited for applications where its characteristics of high dielectric strength, stability, low temperature sensitivity, and good EMI/EMC performance are required.

The B32620J0222J189 capacitor operates on the principle of electrostatic field. When dielectric material is placed between two conductive plates, the dielectric material creates an electrical field. This field accumulates charges on the plates and stores energy. The electric field also blocks current from passing through the dielectric material and only let a portion of the current to travel through. By adjusting the thickness of the dielectric material, these capacitors can be adjusted to have different capacitance values. The capacitance of the B32620J0222J189 is specified as 2.2 μF.

The B32620J0222J189 capacitors are designed to tolerate higher voltage and current than other film capacitors. Its metalized polyester dielectric material is designed to survive up to 450 volts, while other film capacitors usually have a maximum voltage of 250 volts. This makes it suitable for use in demanding applications where high operational voltages are required. Its rated operating temperature range is -40 to 85°C, and its specific impulse power is 490 volts. The relative permittivity is 5.7.

In summary, the B32620J0222J189 capacitor is ideal for many applications where high performance and reliability is necessary. Its relatively high capacitance, high voltage rating, and low ESR make it suitable for power supply, overvoltage protection, and ripple current control applications. Its simple working principle and high dielectric strength make it reliable for long-term use.
