Working Principle of the APXG250ARA220MF45G

The APXG250ARA220MF45G works on the principle of electrostatic conduction. This is a process in which an electrical charge is stored on the inner surfaces of two conductive plates which are isolated by an insulation layer. The two plates are connected to an external circuit, and the stored charge is used to control electricity passing through the circuit. When a voltage is applied to the capacitor, electricity is drawn from the capacitor, reducing the amount of stored charge. This in turn affects the amount of electricity passing through the circuit. The capacitor is then recharged by the external circuit.

The capacitance of the APXG250ARA220MF45G is determined by the size and shape of the plates and the type of dielectric material between them. The higher the capacitance, the more charge the capacitor can store and the larger the voltage drop. This makes the APXG250ARA220MF45G a versatile choice for applications that require high current, high voltage and high frequency switching. The capacitor is also rated for a maximum temperature of +125°C, making it suitable for high temperature applications.
