Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are capacitors used in electronic circuits that rely on an oxide in a dielectric fluid or a solid-state electrolyte on a surface of a thin anodic aluminum foil for their functioning. They are mainly used in power applications for storing energy, attenuating voltage spikes, and filtering. The electrolytic capacitors are more versatile than other types of capacitors, and can be found in a variety of electrical applications.

LGJ2G221MELC20 Application Field and Working Principle

The LGJ2G221MELC20 aluminum electrolytic capacitor is used for high frequency applications, such as storage, input/output coupling, signal processing, high frequency interstage coupling, and high frequency rectifier. It\'s capacity are 270uF-2200uF, maximum working voltages are 6.3V to 140V, and its maximum working temperature range is -40°C to +105°C. This capacitor works based on the principle of electrochemical charge storage where an anode aluminum foil is separated from a dielectric oxide film and bonded together using a liquid or solid state electrolyte.

The electrolyte, which is typically an alkaline solution, serves as a medium for transporting electrical charge to and from the anode and dielectric layers, allowing for an exchange of electrons between the two components. This process creates an electric field around the capacitor and stores charge within the dielectric. The stored charge on one side of the capacitor increases while the other side decreases, allowing the capacitor to carry a steady voltage and current across its terminals.

When the capacitor is in operation, the electrolyte acts as an insulating medium between the anode and cathode. This prevents the electrons from being lost and allows for a steady current to flow between the two components. The dielectric layer also limits the amount of current passing through the capacitor, ensuring that it is not overcharged or undercharged.

The LGJ2G221MELC20 aluminum electrolytic capacitor has several advantages, such as being able to store large amounts of charge, a wide temperature range, and excellent electrical stability. It is also a low cost capacitor with a long lifespan and a low self-discharge rate. This makes it ideal for a wide range of applications, such as power supply filtering, signal processing, and high frequency rectifier.
