Introduction

Film capacitors, also known as plastic film capacitors, are widely used in electronic circuits due to their high stability, insulation and reliability. B32672L1153K289 is a type of film capacitor with excellent performance. This article will introduce the application field and working principle of the B32672L1153K289 film capacitor.

Application Field

The B32672L1153K289 film capacitor is mainly used in automotive electronics, industrial electronics, communications and other related products. It is suitable for applications that require higher levels of temperature, high ripple current or working in severe vibration and high altitude environment.

The capacitor with excellent performance is also widely used in other aspects, such as high-quality audio equipment, switching power supply, and aircraft electronics. Due to its stability, the capacitor can also be used in other fields where stable capacity requirements are needed.

Working Principle

The B32672L1153K289 film capacitor is made up of two thin-film layers made of plastic, one of which is metalized and insulated. When alternating current flows through the capacitor, electrical charge is accumulated on the inner layer, while the two layers are closely connected. The energy storage capacity of the capacitor is determined by the thickness of the film and the total area. The charge is constantly flowing between the plates, and the capacitor acts as a conductor, allowing small alternating currents to pass through.

Film capacitors are usually used in circuits where small amounts of low-frequency AC signals or DC voltage levels need to be filtered, and the presence of a dielectric material between the electrodes allows the storage of electrical energy. The capacitor also eliminates any sudden changes in current, smoothing out electrical waveform, thus reducing EMI and RFI.

Conclusion

The B32672L1153K289 film capacitor is a high performance device with many advantages such as stability, insulation, and reliability. It is widely used in automotive electronics, industrial electronics, and communications, as well as audio equipment, switching power supply and aircraft electronics. The working principle of the capacitor is based on the exchange of charge between the two thin film layers, allowing small alternating currents to pass through and thus reducing EMI and RFI.
