Aluminum electrolytic capacitors (AEC) are widely used for many different applications in electronic circuits. They are able to store electrical energy and are available in very large and small sizes. However, due to their high capacitance and higher voltage ratings, they are often used in applications demanding high power and safety. One such capacitor is the LGU1C183MELA. This article examines the application field and working principle of the LGU1C183MELA.

The LGU1C183MELA aluminum electrolytic capacitor is designed with a large capacity of 15000uf and a rated voltage of 35V. It also has a very low ESL (Equivalent Series Resistance) value of 1.4 ohm and a fast-acting capacitance of 18000uf. This makes it suitable for applications requiring large amounts of stored energy and for applications which need to be quickly energized. It can be applied to power supplies, motor drives, and high power switching applications in automotive, industrial and audio circuits.

The working principle of the LGU1C183MELA aluminum electrolytic capacitor is based on the principle of electrolysis. The capacitor is composed of two electrodes separated by an electrolyte. The electrodes are composed of a conductive material, typically aluminum, and the electrolyte is composed of a mixture of an acid and water. The electric current through the electrodes causes an electrochemical reaction between the electrolyte and the electrodes, forming a thin oxide film on the surface of the aluminum electrode. This oxide film acts as an insulator between the two electrodes and thus stores the electrical charge.

The LGU1C183MELA aluminum electrolytic capacitor is a Leclanché type capacitor in which the electrochemical reaction is reversed by applying a voltage in the opposite direction. This causes the oxide film to break down and the stored electrical charge to be released into the circuit. In order to prevent the oxide film from reforming, a reverse leakage current is employed. This leakage current limits the amount of charge that can be stored and thus prevents the capacitor from overcharging.

The LGU1C183MELA aluminum electrolytic capacitor is an excellent choice for applications which need large amounts of stored energy, fast energizing, and high power. Its high capacitance, low ESL value, and fast-acting capacitance make it well suited for use in a variety of power supplies, motor drives, and high power switching applications. The reversed electrochemical reaction ensures that it can be repeatedly charged and discharged, providing a reliable and long-lasting solution to power needs.
