Aluminum electrolytic capacitors are widely used in electronic technology due to their high dielectric strength, high energy density, and small physical size. The LQR2W123MSEJBN is one of the most popular types of aluminum electrolytic capacitors. In this article, we will discuss the LQR2W123MSEJBN application field and working principle.

Application Field

LQR2W123MSEJBN aluminum electrolytic capacitors are used in many different applications within the electronics industry. It is commonly used as a power filter in power supplies, as a coupling or bypass capacitor in signal processing circuits, and in high power audio applications such as loudspeakers or amplifiers. It is also used as an energy storage device in high power LED lighting applications such as streetlights.

Working Principle

The LQR2W123MSEJBN utilizes the principles of electrolytic capacitance. It is constructed of a metal oxide film as its anode electrode, which is then rolled up and sealed in a cylindrical metal enclosure and filled with an electrolytic solution containing an alkaline or acidic electrolyte. The cathode is then connected to the container\'s lid via a wire. An electrostatic field forms between the anode and cathode and creates an electric charge across them. This charge creates a capacitance effect that allows electric current to flow between the two electrodes when a voltage is applied.

The amount of electric current that can be drawn from the capacitor depends upon the amount of charge stored in its electrodes. This charge can vary depending on the magnitude and direction of the applied voltage, the electrolyte used, the temperature of the capacitor, and the type of metal oxide film used in the anode.

By combining the principles of electrolytic capacitance and the ruggedness of a sealed metal container, the LQR2W123MSEJBN is an ideal choice for numerous applications within the electronic industry.
