Working Principle of EKMS421VSN151MP35S

An aluminum electrolytic capacitor consists of two aluminum foils separated by a porous paper spacer and immersed in an electrolyte solution. Electrolytes used in aluminum electrolytic capacitors are usually polyethylene oxide (PEO) or ethylene carbonate (EC). When a potential difference is impressed across the electrodes, ions move to the positive electrode, which creates an electrical field between the two electrodes, resulting in electrical energy storage. The capacitance of an electrolytic capacitor is determined by the size of the electrolyte, the number of electrodes, and the area of the electrode surfaces.

The primary advantage of aluminum electrolytic capacitors is that they have a larger capacitance than ceramic capacitors, making them suitable for high frequency applications. In addition, aluminum electrolytic capacitors have lower impedances, which makes them more suitable for low-frequency signals such as DC and audio signals. Furthermore, they have a relatively low ESR (equivalent series resistance), which makes them suitable for high-power applications.

In addition to the above, aluminum electrolytic capacitors have a long life expectancy, resistant to high temperatures, and low leakage. Because of these advantages, aluminum electrolytic capacitors are widely used in a variety of applications. The EKMS421VSN151MP35S is an example of a specialized aluminum electrolytic capacitor designed for the toughest conditions.
