Aluminum Electrolytic Capacitors

LAR2W121MELA30 application field and working principle

Aluminum electrolytic capacitors are energy storage components widely used in various electronic circuits to provide the energy required for signal transduction and process control. The LAR2W121MELA30 aluminum electrolytic capacitor is manufactured by Nichicon and is a radial, non-solid, through-hole capacitor. It is a type of aluminum electrolytic capacitor and its structure consists of an aluminum envelope, an electrolyte, and two pieces of aluminum foil.

The application field of the LAR2W121MELA30 aluminum electrolytic capacitor mainly include such wide applications as power supply systems, power switching circuits, control circuits, motor drives, AC-DC converters and other related operations. Its working principle of the LAR2W121MELA30 aluminum electrolytic capacitor is simple. On the one hand, the electrolyte is a liquid that acts as an insulator and electrolyte to maintain the bias of the capacitor. At the same time, it is also used to periodically restore the charge to the capacitor. On the other hand, the two aluminum foils of the unit form the capacitor electrode.

When the charging voltage is applied, the aluminum foil inside the aluminum envelope becomes positive and the outside becomes negative. When the voltage is applied, due to the difference of charge between the two electrodes, a large electrostatic force is generated, thus forming an electric field. As the voltage is increased, the electric field between the electrode gap is also increased, which increases the capacitance. When the charging power is provided, the electric field is reversed, and then a certain amount of charge stored in the capacitor can be released. The electrical energy stored in the capacitor is thus released.
