Aluminum Electrolytic Capacitors: LGG2C681MELA25 application field and working principle

Aluminum electrolytic capacitors, also known as dark capacitors, are commonly used storage components. It is mainly composed of aluminum electrolytic foil, electrolyte solution, separator and other components. The aluminum electrolytic capacitor is characterized by large capacitance and small volume. It has the advantages of high charge and discharge rate, reliable sealing performance, low leakage current and strong oxidation. The product’s long-term stability and high reliability makes it widely used in audio systems, switch power, instrumentation, automotive electronics, fish finders, air conditioners, smart homes, electronic ballasts, cellular antennas, cordless phones and other fields.

Working Principle of LGG2C681MELA25

The aluminum electrolytic capacitor uses aluminum oxide as the dielectric material. It combines different metal layers to form a three-layer structure under certain conditions. The middle layer is used as the dielectric, and the two sides are used as the electrodes. The three layers are inlaid and pressed into one body. The electrolytic conductor is filled with an electrolyte (ethylene glycol, propylene carbonate, etc.), and the positive pole is connected to the aluminum foil. When a DC voltage is applied, due to the effect of the potential barrier generated by the oxide film, ions will begin to move in one direction in the electrolyte, forming the capacity in the capacitor. The high-purity aluminum foil has a better oxidation effect during the reaction, so it is widely used.
