LGW2D681MELZ40

Aluminum electrolytic capacitors are widely used in switching power supplies, power converters, automotive electronics and other sectors with its merits of being smaller in size, higher in power density, lower in equivalent series resistance and higher in capacitance. In terms of such capacitors, LGW2D681MELZ40 belongs to the mid-to large-size models.

The technology of LGW2D681MELZ40 aluminum electrolytic capacitors combines the unique characteristics of aluminum electrolytic technical process and high temperature endurance technology, which is suitable for producing high quality and long-term stable capacitance electrochemical capacitor. This capacitor is mainly used in the high-frequency filter, discharge circuit and charging circuit. It can also be used in power converters as a filter or Energy Storage, and in switching power supply circuits, inverters, automobiles and other related areas.

The working principle of aluminum electrolytic capacitor is based on Faraday\'s law. The aluminum foil and electrolyte (insulating liquid) inside it constitute a electrochemical structure, which can generate electrostatic capacitance. According to Faraday\'s law, when a direct current (DC) passes through the aluminum foil and electrolyte, it charges the aluminum foil, forming a so-called electric double layer. The electric double layer acts as a storehouse, which is equivalent to the capacitor dielectric layer that stores the electrical energy.

As a kind of aluminum electrolytic capacitor, LGW2D681MELZ40 has higher power and voltage, good frequency capability, and high charge and discharge performance. It is electrolytic paper and film-flexible aluminum foil paper-aluminum foil, non-solid electrolyte, and the shells and external electrodes use metal materials, aluminum, etc. Its internal connection is welding external connection is welding and soldering.
