Aluminum electrolytic capacitors are among the most commonly used types of capacitors. They offer relatively high capacitance values in small packages and are often used in filter circuits, timing circuits, amateur radio applications, low and medium frequency amplifiers, and high power devices. The LGG2E102MELB40 is a popular aluminum electrolytic capacitor from the LGG2E series, offering an operating voltage of 450 VDC and rated capacitance of 22 µF. Unlike other aluminum electrolytic capacitors, the LGG2E102MELB40 operates in a temperature range of -25 to +85°C, making it suitable for applications in extreme environments.

The working principle of aluminum electrolytic capacitors is based on the action of an electrolyte ionizing a solid aluminum oxide film. When a DC voltage is applied, the oxide film is polarized by the effects of the ions in the liquid electrolyte, creating a charge on the two aluminum surfaces. This charge increases with the applied DC voltage and the aluminum surfaces become polarized. This polarized surface is what creates the electric field inside the capacitor and enables it to store a charge.

The LGG2E102MELB40 aluminum electrolytic capacitor is designed for use in a wide range of applications, including DC DC converters, high-speed switchers, pulse power supplies, microwave ovens, power amplifiers, and general-purpose circuits.
