Aluminum Electrolytic Capacitors are a type of capacitor that uses aluminum oxide plates to conduct electrical energy. The ELXM221VSN391MP40S is a specific type of Aluminum Electrolytic capacitor that is designed for applications requiring high voltage and high temperature.

Application Field and Working Principle

The ELXM221VSN391MP40S is ideal for applications requiring high frequency, high temperature, and high voltage. For instance, the capacitor can be used in power supplies, audio amplifiers, and electric motors, or any application where a high-temperature, high-stability, reliable power source is needed. The capacitor has a capacitance of 2200µF and a rated voltage of 400V.

The ELXM221VSN391MP40S works on the principle of electrolytic action - a type of ionic action that takes place between two plates of aluminum in an electrolyte. The plates are electrically polarized by trapping oxide ions within the layers of electrolyte. When a current is applied to the plates, the polarized oxide ions move around, creating a "double layer" of charge at each plate. This double layer of charge produces a strong electrical field across the plates. As the voltage across the plates increases, the oxide ions are pushed further apart, resulting in an increase in capacitance. At the same time, the capacitance decreases as the voltage across the plates decreases.

The ELXM221VSN391MP40S is also designed to perform reliably in high temperatures. The electrolyte acts as an insulator and prevents oxidation of the aluminum oxide plates. In addition, the electrolyte is designed to release heat from the aluminum oxide plates, allowing them to operate at higher temperatures without damage. This makes the capacitor suitable for use in applications that require high voltages, high frequency, and high temperatures. Additionally, the capacitor is noiseless, which is beneficial for audio amplifiers.

The ELXM221VSN391MP40S is also designed with an internal impedance that resists higher frequency signals. This reduces electrical losses, extends the life of the capacitor, and allows for a more consistent output performance. Additionally, the low impedance of the capacitor further enhances the stability and reliability of the device.

In summary, the ELXM221VSN391MP40S is an ideal Aluminum Electrolytic Capacitor which can be used in a variety of applications requiring high voltage, high frequency, and high temperature. Its internal impedance prevents electrical losses, and its electrolyte is designed to prevent oxide damage and release heat. The capacitor is also noiseless and has a low impedance for consistent performance.
