Aluminum electrolytic capacitors are components that use the principle of electrochemical capacitors to store energy in electronic circuits. They are widely used in a variety of industrial and consumer applications, including the LQR2G392MSEH.

The LQR2G392MSEH is a radial, aluminum electrolytic capacitor created by Mitsubishi. It is categorized as a non-solid capacitor, with an operating temperature of -55°C to 105°C. The most common application of the LQR2G392MSEH is to act as the decoupling capacitor in a DC/DC switching power supply system. The device works to provide a constant voltage ripple to the output of the converter, ensuring that its performance is not compromised by AC-generated noise in the power system.

In addition to power supplies, the LQR2G392MSEH is used in a variety of other applications, including computer memory, solid state drives, audio systems, and medical systems. It is noted for its ability to tolerate higher temperature extremes, and for its stability over time. It is also relatively low cost, making it a good option for applications where price is a consideration.

The working principle of the aluminum electrolytic capacitor is based on the use of an electrolyte to create an electrical field. The capacitance of the unit is created by a thin oxide layer that forms between the two electrodes in the presence of the electrolyte. This layer acts as an insulator between the two electrodes, which allows the capacitance to increase drastically compared to air capacitors, and provides an increase in current and voltage capacity.

In the LQR2G392MSEH capacitor, the two electrodes are a pair of aluminum foil leads that are separated by a spacer. The electrodes are immersed in an organic electrolyte made of a combination of organic solvents and other additives. When an electric field is applied to the assembly, an oxide film forms on the electrodes that acts as an insulator. This allows the capacitor to store a large amount of charge, which is released when the electric field is removed.

The aluminum electrolytic capacitor is a common, reliable, and cost-effective component that is used in a variety of applications. The LQR2G392MSEH is a high-performance aluminum electrolytic capacitor that is capable of tolerating increased temperature extremes and provides a high level of stability over time. Its most common use is in DC/DC switching power supplies, but it can also be used in other applications such as audio systems, medical systems, and computer memory devices.
