Working Principle

The working principle of the 474PSB202K2J film capacitor is based upon storing electric charge in the capacitor’s dielectric material. When an electric voltage is applied between the two electrodes of the capacitor, electric charge is stored in the dielectric material. The amount of electric charge stored in the dielectric material is determined by the voltage applied to the capacitor and the capacitance of the capacitor. When the applied voltage is removed, the electric charge stored in the dielectric material is slowly released, which will form a current through the capacitor. This current will be determined by the capacitance of the capacitor and the rate of release of electric charge from the dielectric material.

Conclusion

The 474PSB202K2J film capacitor is a reliable and versatile capacitor that is suitable for a wide range of applications. It has excellent electrical properties, is compact and lightweight and has a range of features that make it suitable for use in high-temperature environments, consumer electronics, automotive and medical applications. The working principle of the 474PSB202K2J is based upon storing electric charge in the dielectric material and allowing it to be slowly released when the applied voltage is removed.
