LGJ2G820MELB

Aluminum electrolytic capacitors are the most common type of capacitor. They are used in electronics because of their superior stability, high capacitance, and low cost. The LGJ2G820MELB is an example of an aluminum electrolytic capacitor featuring double-sided capacitor plates and a long life of over 5000 hours at 105°C. It is suitable for high voltage applications in the industry, such as motor controllers, power supplies, and communication systems. It can also be used in a variety of automotive applications, including alternators, electric power steering, and fuel injection systems.The LGJ2G820MELB is a non-polar, aluminum electrolytic capacitor with a low Equivalent Series Resistance (ESR) of less than 0.5 ohms. This helps to keep the capacitor’s voltage much closer to its rated value during operation, preventing any sudden voltage drops that can cause damage to other components. It also has a high ripple current rating of 270A, allowing it to handle intense waveforms without shortening its lifespan or affecting its performance. The low temperature coefficient of -40PPM/°C, along with its high capacitance tolerance of ±20%, ensures consistent performance in both hot and cold temperatures.

The working principle of the LGJ2G820MELB is similar to any other aluminum electrolytic capacitor. It contains two Aluminum Foil Plates, anode and cathode. The anode is usually the positive plate, while the cathode is the negative plate. Between these two plates there is a thin layer of electrolyte, which acts as a dielectric. When a voltage is applied, ions from the electrolyte migrate to the anode and cathode, allowing current to flow through the device. This current then forms a field between the plates, which stabilizes the voltage between them.

The LGJ2G820MELB is an ideal choice for applications requiring a long life, high capacitance, and low ESR. Its double-sided capacitor plates and long life make it suitable for industrial applications, such as motor controllers and power supplies. It is also well-suited for automotive applications, like alternators, electric power steering, and fuel injection systems. Its low ESR and temperature coefficient of -40PPM/°C provide stable operation in extreme conditions, while its high ripple current rating of 270A makes it ideal for high energy applications.
