Aluminum electrolytic capacitors, commonly known as "electrolytics", are the most commonly used capacitors. They are composed of two conducting aluminum foils, made of pure aluminum, with an electrolyte between them. The 381LQ821M180H042 is an aluminum electrolytic capacitor with a working voltage of 81 volts and a rated capacitance of 180μF.

The aluminum electrolytic capacitor is the most common capacitor. It is available in a wide variety of styles and values and is used in many applications from power supplies to steering systems, audio amplifiers to decoupling circuits. The working principle of the 381LQ821M180H042 is simple and straightforward. When voltage is applied, the electric charge on the aluminum foil increases, causing the foil to become polarized. This polarizes the electrolyte which conducts electrons between the aluminum foils, allowing current flow.
