Aluminum electrolytic capacitors are widely used in industry, as they can effectively store and filter electric energy and reduce voltage distortion. The LGW2E681MELC25 is an aluminum electrolytic capacitor with good performance. It is usually used in some relatively harsh environments, such as higher temperatures and higher pressures.

The LGW2E681MELC25 has a rating of 6.8µF/2V. It has an operating temperature range of - 40℃ to + 125℃, and a long life of 2000 hours at + 125℃. The capacitor has a good surge voltage capability of 1600V (5ms). In the application, because of its small size, the LGW2E681MELC25 can meet the requirements of many harsh environments and can realize high-density applications.

LGW2E681MELC25 is constructed of aluminum (electrode plate), electrolyte, and metal casing. In this case, aluminum is anode and one of the electrodes, and the electrolyte is a conductive solution, while the metal casing forms the outer casing and also serves as one of the electrodes. At the same time, the capacitor also uses a vented long-life venting method, which effectively reduces the corrosion of electrolytic capacitors, ensuring the sealing of the capacitor.

The working principle of the LGW2E681MELC25 capacitor is simple. With the application of the external high-voltage power supply, a certain amount of electricity is generated, causing the electrolyte to corrode and form an electrolysis film on the surface of the aluminum film. This film gradually increases, thus forming a very thin layer of dielectric film on the surface of the aluminum film. At the same time, an electric field is formed between the electrodes, thus increasing the storage effect of the capacitor. By varying the voltage and current in the capacitor, the capacitance can be varied, and the circuit can be tuned and adjusted.

The LGW2E681MELC25 capacitor can be widely used in many occasions, such as the filter of the frequency domain, no-load compensation load, and the surge resistance acceleration of converter system, inhibiting contactor bounce, and soft starting of motor, etc. It can be used not only in traditional electronic equipments, but also in today’s industrial production always using precision instruments, robots, and unmanned automation equipments.

Overall, LGW2E681MELC25 aluminum electrolytic capacitors are widely used in industry, because of their good performance, safety, durability, and reliable operation. Its small size also makes it an ideal replacement for other larger equivalents, while the thick electrolyte and long life venting method make it a better choice for harsh environments.
