Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are electronic components which can store electric energy in an electric field. They are widely used in the electronic products and circuits. In the application field and working principle of aluminum electrolytic capacitors, the specific code number -- 381LX181M400K032 is very important in electronic products.

Aluminum electrolytic capacitors are mainly used in switch power, LCD backlights, motor driver, servo actuator, electric tool, electronic medical device, automobile electronics, solar inverter, etc. The 381LX181M400K032 aluminum electrolytic capacitors are smaller in size, more flexible in design and better in performance compared to other aluminum electrolytic capacitors of the same capacity.

The working principle of aluminum electrolytic capacitors is the electrochemical effect. This type of capacitor works according to the principle of Faraday\'s law of electrochemical equivalent. Electrolytic capacitors consists of an anode, cathode and electrolyte. The anode of the aluminum electrolytic capacitor that is 381LX181M400K032 is a metal oxide that is etched out of aluminum foil with an electrolyte solution. The electrolyte injection makes the metal oxidation on the anode react with aluminum oxide to form an insulating layer. The insulating layer is porous and allows the electrons to move through it to form a path between the anode and cathode. There is a thin layer of electrolyte solution between the two capacitors. When electric energy is supplied to the capacitor, the electric field interacts with the electrolyte and generates current.

The characteristics of aluminum electrolytic capacitors are good insulation, high energy density, wide frequency range and higher stability. Their major features are high ripple current, low equivalent series resistance and low temperature coefficient.
