Film capacitors are generally divided into plastic film capacitors, paper film capacitors and metal film capacitors. They are not easily affected by temperature and humidity and have high insulation properties. Plastic film capacitor has the advantages of small size, light weight, wide range of capacitance, good insulation, high precision, large capacity and long life. It is an ideal choice for voltage moveover circuit. 155PSB102K2J is a plastic film capacitor with a breakdown voltage of 250V and a capacitance of 10uF. Here I will introduce you about the application field and working principle of this product.

Application Field

155PSB102K2J is mainly used in audio system voltage amplifier circuits, loudspeaker drive circuits, microphone circuits, power supply oscillation circuits, pulse circuits, resonant circuits and the like. In the voltage selection process, it can accurately apply the required voltage and give the circuit a certain capacitance absorption. This capacitor has a good working temperature and shelf life, which can maintain stable signal transmission.

Working Principle

155PSB102K2J is a film capacitor made with a plastic film as the dielectric medium. When an alternating voltage is applied between the two poles of the capacitor, an alternating electric field is generated between the two poles. This alternating electric field causes the media to selectively pass electric charges through the dielectric layer and accumulate them on the surface of the media. When the two electrodes accumulate enough electric charge, the capacitor can be filled with electric charges, so that the electric charges stored in the capacitor can form an electric field between the two poles, thereby forming a certain capacitance.

When a DC voltage is applied to the two poles of the capacitor, the capacitor will not store electric charges, and the capacitance of the 155PSB102K2J will decrease with the increase of the voltage applied to the two poles. When the voltage to the two poles is greater than the breakdown voltage, the capacitor will be in a breakdown state, causing a sharp increase in the current of the circuit.

In addition, due to its low ESR, good temperature characteristic and low loss, it can improve the stability of the whole electronic circuit operation and reduce the influence on the signal by interference. These features make the 155PSB102K2J more efficient and reliable.

Conclusion

In conclusion, the 155PSB102K2J film capacitor is mainly used in audio and electronic systems, and its working principle is the use of a plastic film as a dielectric medium to create a certain capacitance. This capacitor has features including high insulation properties, small size, light weight, wide capacitance range, high precision, large capacity and long operational life. All these advantages make the 155PSB102K2J a reliable and efficient choice.
