Working Principle of ULD2W220MHD6 Aluminum Electrolytic Capacitors

ULD2W220MHD6 aluminum electrolytic capacitors are composed of three functional components: anode, cathode and electrolyte, and one insulation component: dielectric. Like other polar capacitors, the ULD2W220MHD6 also belongs to the electrolytic capacitor. It is also called wet capacitor or electrolytic capacitor. Its basic working principle is the same as other electrolytic capacitors.

The working principle of ULD2W220MHD6 aluminum electrolytic capacitor is based on chemical reaction: The alternately negative and positive electric charge of capacitor plates will cause the opposite migration of ions from electrolyte such as sulfuric acid to anode and cathode plates. This is what makes the load capacity of ULD2W220MHD6 Capacitor depend on the pressure of an electrolyte. The move of ions will generate an electric layer on the surface of both anode and cathode plates. Oppositely charged particles will come together to form a barrier so that the electric charge cannot pass through. This is the working principle of ULD2W220MHD6 Aluminum electrolytic capacitor.
