LGY1H682MELA45

An aluminum electrolytic capacitor is a type of electrolytic capacitor and a component for storing electrical energy and releasing it quickly, typically for higher frequencies and in higher voltage applications. It consists of two aluminum foil electrodes separated by a dielectric layer which is the dielectric liquid electrolyte, which is actually a paste consisting of aluminum oxide, the electrolyte liquid and additives including surfactants. The aluminum foil electrodes have a large surface area meaning that the capacitance values can be kept high and the amount of electricity stored per capacitor can be kept high. The design of aluminum electrolytic capacitors includes a number of features to enable safe and reliable operation in many applications, including over-voltage protection, corrosion protection and EMI shielding.

LGY1H682MELA45 application field and working principle

The LGY1H682MELA45 is an aluminum electrolytic capacitor designed specifically for use in high-voltage and high-frequency applications. It features a cathode made of an aluminum foil and an anode made of an incredibly thin porous layer of alumina. This capacitance provides an excellent combination of high volumetric efficiency, low ESR and long operating life. It also features a high temperature range of up to 105°C, making it suitable for use in applications requiring elevated temperatures.

The working principle of LGY1H682MELA45 is based on the Faraday\'s Law. When a voltage is applied across the capacitor, the anode is flood charged by the current. The anode is then polarized and a dielectric film is created between the anode and the cathode. This dielectric film stores the energy as a form of electrochemical charge and serves to block the current from crossing between the electrodes. This effect enables the capacitor to store the energy required for any current demanding application.

LGY1H682MELA45 can be used in a variety of high-voltage and high-frequency applications, ranging from small portable electronic equipment and automotive systems to high-voltage power supplies, electronic switching circuits and RF amplifiers. Its robust structure and long operating life make it suitable for applications where high temperature and high current loads are expected. Furthermore, its design offers protection against over-voltage, EMI, and corrosion.
