Aluminum electrolytic capacitors consist of two aluminum foils with an insulating material (typically paper in an orange oil impregnated with) covering the aluminum plates called the so-called cathode electrolyte, which is in contact with an electrolyte (various organic solvents-based electrolyte) and a pressure-foil to form the positive pole. The so-called anode, and the other aluminum foil is the so-called cathode, each of the aluminum foils has a layer of oxide film on its surface. This oxide film acts as the dielectric and it is responsible for the capacitance of the capacitor. The oxide film also acts as an insulating layer between the anode and the cathode.

A 400HXG100MEFCSN22X25 aluminum electrolytic capacitor is an electrolytic capacitor with a higher capacitance, higher dissipation and tailored for long shelf-life. The capacitor has a cylindrical case, usually with axial leads, in which the anode is surrounded by either a liquid or solid electrolyte. It has an average capacitance range from 0.1µF to 10,000µF, a working voltage of up to 450V, and a temperature range of -55°C to +105°C. 400HXG100MEFCSN22X25 capacitors are typically used in AC applications and in DC applications with periodic polarity reversal.

The main application fields of 400HXG100MEFCSN22X25 aluminum electrolytic capacitors are motor control systems, welding machines, AC power converters and other applications that require high capacitance and high voltage. In motor control systems, the capacitor is used to reduce the voltage ripple of the starting motor and also to reduce the starts and stops of the motor. In AC power converters, it is used to reduce the voltage between the two voltage lobes of the power grid and also to reduce the high frequency noise. In the welding machines, it is used to store the electric energy and reduce the welding current noises.

The working principle of a 400HXG100MEFCSN22X25 aluminum electrolytic capacitor is quite simple. When a voltage is applied between the electrodes, it causes a chemical reaction between the electrolyte and the oxide layer on the two aluminum foils, resulting in a relatively large number of negative and positive charges being created on the two foils. This creates a strong electric field between the foils, creating a current flow and an electric charge on the capacitor which is stored as a voltage across the capacitor. This voltage is then available to be used in the circuit.

To ensure good performance and reliability of the 400HXG100MEFCSN22X25 aluminum electrolytic capacitor, it is important to use the correct type of capacitor for the application. The capacitor should be chosen for the particular application and it is important to select the correct capacitance, voltage and temperature rating for the application. In addition, proper maintenance and care should be taken to ensure proper performance of the capacitor.
