Working Principle

The R474W422500K film capacitor works to store electric energy and reduce power loss through dielectric absorption. In its operation, a dielectric film and conductive electrodes are placed between two metal leads, creating an electric field and charging electric energy. When an alternating current is applied to the leads, the electric field will cause electrical charges to be stored in the capacitor, causing the voltage at both contacts of the capacitor to be changed. When there is an average voltage between the two contacts, energy is released back to the circuit, and the energy stored in the capacitor\'s electric field is slowly reduced.

During discharge, the energy stored in the capacitor\'s electric field is slowly reduced, and the electric charges on both leads of the capacitor become zero, so that the current that passes through the capacitor is also 0. When the voltage is changed, the resistance between the two leads of the capacitor also changes, so that the current is affected. This process is continuous and causes dielectric losses and heat generation. The good quality of the dielectric material of the R474W422500K film capacitor ensures that the power loss remains at a low level under most working conditions, even when the temperature is increased.
