Aluminum electrolytic capacitors are electrical components that store electrical energy temporarily. They are widely used in all kinds of electronic circuits, such as AC/DC solid-state lighting, LED lighting, audio circuits, telecommunication systems, and motor drives, among other applications. The LGJ2E391MELC20 is a long-life aluminum electrolytic capacitor specifically designed for use in these applications. It features a long operating life, low leakage current, and high ripple current capability without compromising on quality or safety.

The LGJ2E391MELC20 aluminum electrolytic capacitor is a small, axial type capacitor with a rated capacitance of 1μF. It is composed of a cylindrical anode made from an aluminum foil, and a cathode made from nickel-plated steel. The aluminum foil is etched with a pattern that forms the capacitor’s capacitance. The entire anode is wound up with an electrolyte-soaked paper spacer, and the entire package is enclosed in a plastic sleeve. The LGJ2E391MELC20 is rated for a voltage of 25V and a temperature range of -40°C to +85°C.

The operating principle of an aluminum electrolytic capacitor is fairly simple. When a voltage is applied to the capacitor, electrons will flow from the cathode to the anode, and an electric field builds up in the space between the two electrodes. This electric field causes an accumulation of charge on the anode, and the capacitance of the aluminum electrolytic capacitor is dependent on the applied voltage and the physical area of the anode. As the applied voltage increases, the capacitance also increases. Likewise, the capacitance decreases as the voltage decreases.

The LGJ2E391MELC20 is specifically designed for use in AC/DC solid-state lighting and LED lighting applications. Its long operating life and low leakage current make it ideal for these applications. The LGJ2E391MELC20 can also be used in audio circuits, telecommunication systems, motor drives, and other applications that require a low-torque mounting option. Additionally, its high ripple current capability makes it an ideal choice for applications that require a high frequency operation.

In summary, the LGJ2E391MELC20 aluminum electrolytic capacitor is a long-life, low-leakage current capacitor that is specifically designed for use in AC/DC solid-state lighting and LED lighting applications. It also has high ripple current capability and operates over a wide temperature range. The LGJ2E391MELC20 is a reliable and effective component for a variety of electronic circuit applications.
