Aluminum electrolytic capacitors are widely used because of their large capacitance, high breakdown voltage, long life, low equivalent series resistance (ESR), and good frequency characteristics. Among these capacitors, LGU2G391MELC has emerged as one of the most widely used in a variety of applications. This article provides an overview of the LGU2G391MELC electrostatic capacitor, detailing its application field and working principle.

LGU2G391MELC is a surface-mount aluminum electrolytic capacitor with an operating voltage of 2V, which is typically used in electronic circuits such as low voltage RAM applications in PCs and tablet PCs, as well as high-efficiency LED lighting. It features a radial design and an enlarged electrode construction, which increases conductivity and responsiveness even in low voltages. The terminals of the component are nickel-plated for better corrosion resistance, and its dual terminal design encourages more flexible installation. Moreover, the capacitor is sealed with a heat-resistant epoxy resin that ensures exceptional performance in high-temperature applications.

In terms of its working principle, the LGU2G391MELC reference capacitor utilizes electrical current to transfer ions from an electrolyte to the aluminum anode in order to store electrical energy. The capacitor comprises two metal foils separated by an electrolyte, with one of the metal foils forming the anode and the other forming the cathode. The electrolyte is a chemical solution that contains positively and negatively charged ions. When electrical current is passed through the electrolyte, the positively charged ions migrate to the anode and the negatively charged ions migrate to the cathode.

The resulting electron transfer between the two sides of the electrolyte causes a charge to be stored in the electrolyte and thus the capacitor itself. This charge can then be discharged and used to power other electronic components in a circuit. The capacitor larger capacitance – up to 4 times higher than electrolytic capacitors of similar size – allows for both large energy storage and increased energy efficiency.

The LGU2G391MELC electrostatic capacitor is ideal for use in a variety of application fields, including motor control systems, switches, and inverters. It is also used in high-frequency filters and amplifiers, as well as other high-performing devices such as buffer circuits, surge protection devices, and ultra-low noise circuits.

In conclusion, the LGU2G391MELC aluminum electrolytic capacitor is a high-performance, great value device offering exceptional performance in low voltage applications. Its radial design, enlarged electrodes, and unique dual terminal design combined with expansive capacitance, long life, and low ESR make it a reliable solution for a wide range of electronic circuits. Its application field includes motor control systems, switches, inverters, high-frequency filters, amplifiers, buffer circuits, surge protection devices, and other low noise circuits.
