Film Capacitors

A film capacitor (also known as a plastic or dielectric capacitor) is a capacitor of which the dielectric consists of thin plastic film. Film capacitors widely used for power electronics, radio equipment, and automotive electronics.

B32523R0226K000 Application Field and Working Principle

B32523R0226K000 is a MKP professional film capacitor from EPCOS. The capacitance is 0.22μF, and its application field is especially suitable for high frequency switch mode power supplies or mains filter for interference suppression. It operates in a temperature range of -40°C to +100°C and a humidity range of up to 85%, with a maximum voltage of 480VAC.

The working principle of B32523R0226K000 film capacitor is based on the principle of capacitance. A capacitance is a component used to store electric charge and transfer electricity between circuit elements. It consists of two metal plates that are separated by a dielectric material. An electrical charge is stored on the metal plates when a voltage is applied. The charge can then be transferred between the plates when a circuit is closed between the two. When an AC current passes through the capacitor, it blocks the flow of DC current, allowing only AC current to flow. This is how a film capacitor is used in power electronics.

Film capacitors are broadly used in power converters, motors, low-voltage filters, phase-angle controllers, and other electronic applications. In addition, film capacitors are used in AC and DC applications, especially for their low losses, high voltage, and high frequency features. Other uses include power factors correction, audio filters, the elimination of miscellaneous noises, and many other types of capacitance applications.

B32523R0226K000 film capacitors have several advantages over ceramic capacitors, such as low ESR, low DF, and a wide temperature range. This makes them suitable for a variety of applications including motor control, LED lighting, broadband, and DC-DC converters. Furthermore, film capacitors have a long shelf life and can handle repeated voltage stress and temperature conditions with less change in capacitance.

In conclusion, B32523R0226K000 film capacitors are an ideal choice for high frequency switch mode power supplies, mains filter applications, motor control, LED lighting, broadband, and DC-DC converters. They offer a range of advantages including low ESR, low DF, wide temperature range, long shelf life, and can handle repeated voltage stress and temperature conditions with less change in capacitance. Additionally, film capacitors are capable of storing electrical charge and transfer electricity between circuit elements.
