Aluminum electrolytic capacitors are one of the most common and widely used components in electronic circuits.

The EKMZ421VSN221MP35S is an aluminum electrolytic capacitor that is designed for use in high-voltage circuits. It is a high-capacity aluminum electrolytic capacitor, with its maximum rated voltage of 21V and maximum capacitance of 350μF. It also has a capacitance tolerance of ±20%, and temperature coefficients of ±20%.

This device is primarily used in power supply and filtering circuits, specifically those operating in high-voltage environments. It also finds application in audio power amplifiers, AC/DC converters, amplifier frequency dividers, and signal processing circuits. Primarily, it acts as a low-impedance current source or sink for AC and DC signals.

The working principle of the EKMZ421VSN221MP35S is based on the principles of electrochemistry. The device consists of two aluminum layers, separated by an electrolyte medium. The aluminum layers are then rolled together into a cylindrical form and charged with an electrolyte. This causes the formation of a thin film between the layers, which acts as the capacitive element.

The capacitance of the capacitor is determined by the thickness and surface area of the film. When a voltage is applied across the layers, the capacitance of the capacitor increases. The capacitor will then hold a charge, allowing it to act as a storage device. As current passes through the capacitor, the stored charge will be reduced and the capacitance of the capacitor will decrease.

Additionally, the aluminum electrolytic capacitor is designed with a very low ESR, or equivalent series resistance. This allows the capacitor to act as an efficient filter element, passing the desired signal while filtering out the noise. This makes it an ideal choice for use in power supply and signal processing applications.

In summary, the EKMZ421VSN221MP35S is a high-capacity aluminum electrolytic capacitor that is designed for use in power supply and filtering circuits operating in high-voltage environments. Its high capacitance and low ESR make it an ideal choice for applications requiring efficient filtering and storage of electrical energy.
