Working Principle

The working principle of the 381LX471M200J012 capacitor is based on the same principles of all aluminum electrolytic capacitors. The capacitors consist of two highly conductive materials separated by a thin insulating dielectric layer. An anode is composed of a porous aluminum oxide-oxide and is formed penetratively into the of the aluminum base. The cathode consists of a metal foil that is connected to the negative connection.When voltage is applied to the capacitor, the electrical field overcomes the insulating layer forming a conductive path. This produces an electric charge due to the difference of potential between the anode and the cathode. The higher the voltage is, the higher the charge and the capacitance value is.Therefore, the 381LX471M200J012 capacitor provides very efficient energy storage and filtering, in order to reduce noise within electrical circuits.
