Working principle

The 125113U030AH1B aluminum electrolytic capacitor utilizes a standard design consisting of an anode foil, a cathode foil, and electrolytic paper as its main components. The capacitance is created when electrons from the anode foil pass across the dielectric paper and flow toward the cathode foil.

The anode foil consists of an aluminum foil coated with a layer of oxide film. This coating acts as a dielectric, allowing electrons to pass through it and creating the necessary capacitance, depending on the surface area of the foil and the thickness of the coating. The greater the surface area and the thicker the coating, the larger the capacitance.

The cathode foil acts as a conductive pathway for the electrons, connecting the anode and the electrolytic paper. The electrolytic paper acts as the insulation that separates the anode and cathode foils and keeps them from coming into direct contact. It is also responsible for the stability of the capacitor.

The 125113U030AH1B aluminum electrolytic capacitor is a high precision component, manufactured to precise standards. Its excellent performance makes it suitable for a wide range of electronics applications, from telecommunication systems to high-definition audio equipment.
