Aluminum Electrolytic Capacitors are widely used for power handling in electronic circuits. The LGJ2D471MELC is the most common type, due to its ability to handle high voltages in a small package. Its application fields and working principle are explained in detail below.

Application Fields for LGJ2D471MELC: The LGJ2D471MELC is most commonly used in DC power supplies, switch mode power supplies, and other DC to DC converter circuits. It operates at an operating temperature of 125°C and a voltage range of 10 – 250V DC. Additionally, its ripple current rating of 13.3A makes it ideal for rectifier and regulator circuits. The product is also UL approved for safety.

Working Principle of LGJ2D471MELC: The LGJ2D471MELC is a polarized aluminum electrolytic capacitor, where two thin aluminum plates are separated by a dielectric oxide film. The positive plate is coated with rare earth ions, while the negative plate is coated with metal oxide particles, forming a dielectric oxide film between them. This film acts as a separator and allows for highly efficient charge transfer. When voltage is applied to the capacitor, the electric field between the plates polarizes the film, allowing electrons to flow between them and forming a small electric current. This current helps dissipate heat in the capacitor for longer life.

The LGJ2D471MELC is also fitted with a temperature monitoring system, allowing it to remain functional under higher temperatures. It is designed to handle higher voltages and maintain its high capacitance. Its low leakage current also makes it suitable for a wide range of applications.

In conclusion, the LGJ2D471MELC is a high-quality aluminum electrolytic capacitor that is widely used in power handling in various electronic circuits due to its high ripple current rating, UL approval, temperature monitoring system, and low leakage current.
