Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are a type of capacitor that employs an electrolyte to achieve a larger capacitance than other types of capacitors. The most common type is the cylindrical capacitor, which consists of a cylindrical body composed of aluminum as the anode, a dielectric layer, and a cathode made of metal or conductive material. Aluminum electrolytic capacitors are widely used in electronic circuits, and are the predominant form of capacitors used in power supplies, motor drives and other equipment.

LKG1J821MESACK Application Field and Working Principle

The LKG1J821MESACK is an aluminum electrolytic capacitor designed for use in high-frequency and high- power applications. It has a low Equivalent Series Resistance (ESR) and high ripple current capacity. The device consists of two electrodes: a cathode made of conductive material and an anode made of aluminum foil. A dielectric layer is located between the two electrodes, which creates an electric field that stores and produces electric charge.

In a circuit, electric current flows from the anode to the cathode causing the completion of an electric circuit. The voltage across the capacitor varies with the frequency of the applied voltage. The frequency has to be above the resonance frequency for the capacitance of the capacitor to be of any use. The capacitor has a higher impedance at frequencies above the resonance and a lower impedance at frequencies below the resonance.

The primary application of the LKG1J821MESACK is in high frequency and high power applications. It is ideal for use in automotive, telecommunications, consumer electronics, medical equipment and other applications. It can be used in power factor correction circuits, DC/DC converters, SMPS, UPS, telecom and DC motors.

The working principle of the LKG1J821MESACK is relatively simple. When a voltage is applied, the anode layer in the aluminum electrolytic capacitor creates a charge due to the action of the electrolyte. This charge is then transferred to the cathode layer and stored in the dielectric layer. When the capacitor is discharged, the charge is released in an electric circuit.

The LKG1J821MESACK aluminum electrolytic capacitor is a reliable, high-performance device that is widely used in various electronic devices. It is designed to operate under extreme conditions, which makes it well-suited for use in high-frequency and high-power applications.
