Applications of LGL2G331MELA35 Capacitors

Aluminum electrolytic capacitors, also known as electrochemical capacitors, are widely used in a variety of applications. The LGL2G331MELA35, in particular, is an electrolytic capacitor with an electrolyte of aqueous alkaline solution. This makes it particularly suitable for applications requiring a low equivalent series resistance, high ripple current and long life. Some of the applications of LGL2G331MELA35 aluminum electrolytic capacitors include power supply filtering, power line noise filtering and decoupling, heartbeat signals and supervisory circuits. They are also commonly used for anti-interference shielding.

Working Principle of Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor is composed of an anode foil, a dielectric aluminum oxide film, a cathode foil, and an electrolyte. The anode and cathode foils are usually round or oval aluminum foils, etched with multiple slots to form a large number of capacitor cells in the anode. Each cell is separated by electrically insulated foils. The anode foil and the dielectric aluminum oxide film form a porous structure which acts as a buffer between the anode and cathode. The electrolyte is then injected into each capacitor cell and acts as an ionic conductor which aids in the formation of an electric double layer.

When a voltage is applied, electric charges are stored within the oxide film and electrolyte, allowing current to flow through the capacitor until the capacitor is fully charged. During this process, the oxide material on the surface of the anode foil forms a thin film which resists current leakage. This process is known as polarization. This allows the capacitor to store and release energy. The electric double layer formed between the anode and cathode helps in maintaining a constant charge, making this capacitor highly reliable and long lasting.
