Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, also known as aluminum electrolytic capacitors, are components of electronic circuits used to store electrical energy and smooth voltage. A device in which an electrolyte consisting of an aluminum oxide film covered with an electric double layer and non-aqueous liquid, a metal oxide film and a valve film are integrated. Due to the large capacitance, small volume, long life and high reliability of aluminum electrolytic capacitors, they are widely used in industrial and electronic fields, such as trimmers, controllers, LED lights, etc. LDQ2G271MERAGA is one of the common aluminum electrolytic capacitors.

Application Field of LDQ2G271MERAGA

LDQ2G271MERAGA is a miniaturized aluminum electrolytic capacitor that is widely used in power supplies such as switching power supplies, DC-DC converters and ballasts. It is designed to meet the need for higher line filter capacitance and higher power factor correction in a single use. The miniaturized LDQ2G271MERAGA has a maximum capacitance of up to 220μF, which is suitable for applications with limited space while providing excellent ripple current performance.

Working Principle of LDQ2G271MERAGA

The working principle of aluminum electrolytic capacitors consists of four parts: an aluminum foil (anode), an electrolyte solution, a separator consisting of a flexible film impregnated with a non-aqueous liquid, and a cathode consisting of a metal oxide film. The metal oxide film is formed on the anode foil by the reverse anodic reaction of the electrolyte solution, and forms an electric double layer structure that stores electrical energy.

The structure of LDQ2G271MERAGA is similar to that of ordinary aluminum electrolytic capacitors. In order to realize its miniaturization, its anode foil and separator are made of special materials, and its cathode is of special design. When a voltage is applied to the anode and cathode, the capacitor will pass electric current, and the stored electric energy will be converted into heat energy and discharged. Its ripple current can reach 1.2A, and the life is up to 3000 hours at full temperature.

Conclusion

As mentioned above, LDQ2G271MERAGA is a miniaturized aluminum electrolytic capacitors with a wide range of applications in power supplies. By understanding its application field and working principle, people can easily use this aluminum electrolytic capacitor to meet their needs.
