Film capacitors are an integral part of the modern electronics industry. These capacitors are widely employed in applications that require high-frequency impedance, providing capacitance that is very stable over a wide range of temperatures and frequencies. The B32620A3104K189 is an example of a high voltage film capacitor manufactured by global capacitor manufacturer Wima. This capacitor is suitable for applications that require a high capacitance over a wide range of frequencies and offer superb electrical characteristics. This article will examine the application field and working principle of the B32620A3104K189.

Application field of B32620A3104K189

The B32620A3104K189 is a film capacitor that provides a capacitance range of 4.3nF to 1000nF with a rated voltage of 250V. This makes it ideal for use in high voltage and high power applications such as in radio frequency (RF) equipment, automotive audio/video systems, power supplies, switching power supplies, lighting, electro-acoustics and power tools. Its non-inductive and non-polar construction also makes it suitable for use in high-end audio equipment such as audio amplifiers, preamplifiers, microphones and loudspeakers. The B32620A3104K189 also provides excellent reliability and temperature stability with a maximum operating temperature of 125°C.

Working principle of B32620A3104K189

The B32620A3104K189 is a polypropylene film capacitor with an epoxy-impregnated plastic body. This capacitor uses thin polypropylene film as the dielectric material and two metal electrodes which are pressed together to form just a single body. The capacitor is then impregnated with an epoxy resin in order to increase its operating temperature range and humidity resistance. When voltage is applied, electric current flows through the electrodes and passes across the dielectric material. This creates an electric field which causes the electric charges to be displaced and stored as energy, creating a capacitance.

The B32620A3104K189 capacitor works on the same principle as any other electrical capacitor. To increase the capacitance of the capacitor, the physical size of the dielectric material is increased. This increases the area of the electric field and allows more electric charges to be stored at any given voltage. The B32620A3104K189 capacitor has a capacitance range of 4.3nF to 1000nF depending on the size of the dielectric material. The higher the capacitance, the higher the voltage rating of the capacitor.

Conclusion

The B32620A3104K189 is a film capacitor that is suitable for use in high voltage and high power applications. It offers excellent electrical characteristics such as wide capacitance, high temperature stability and excellent reliability. The capacitor works by utilizing thin polypropylene film as the dielectric material and two metal electrodes that are pressed together to form a single body. The capacitor is then impregnated with an epoxy resin to increase its operating temperature range and humidity resistance. The B32620A3104K189 is highly suitable for use in RF equipment, automotive audio/video systems, power supplies, switching power supplies, lighting, electro-acoustics and power tools.
