The working principle of B32642B0393J is based on the capacitive effect between two conducting materials. This effect is the ability of a particular device to store energy in the form of electrical charge. In the case of this capacitor, two sheets of conductive material, which are usually aluminum or copper, are separated by an insulating material called the dielectric. When voltage is applied across these conductive sheets, charge builds up on the sheets and is stored in the capacitor.

Since the capacitor is an energy storage device, the stored energy is released when the electric field is reversed, thus causing current to flow through the capacitor. The amount of charge stored in the capacitor is determined by its capacitance and the voltage applied across its terminals. Therefore, B32642B0393J can be used in a wide range of current and voltage applications, depending on its capacitance and voltage rating.
