Aluminum electrolytic capacitors have been widely used in various electrical appliances because of their long life, small size and large capacitance, and are the most commonly used capacitors. EKMM401VSN221MA25S is one of the typical aluminum electrolytic capacitors.

Application Fields

Aluminum electrolytic capacitors have a wide range of uses in many industries such as aerospace, communications, electronics, computer, automotive, home appliances, and office automation. The EKMM401VSN221MA25S has a wide range of application, such as power filter circuit, DC energy storage, DC-DC converters, frequency converters, and motor drives. It is ideally suited for high current, low impedance, and low noise applications.

Working Principle

Aluminum electrolytic capacitors are composed of an anode, a cathode, and an electrolyte. The anode is made of aluminum foil, which has a very thin oxide film on the surface. The oxide film acts as the dielectric. The cathode is usually a very thin layer of non-conductive paper soaked in electrolyte. The electrolyte consists of an acid (most commonly sulfuric acid) and a salt that creates a solution. When current passes through the electrolyte, an oxide film is formed on the surface of the anode that allows for the charge to accumulate. This is known as the “Farad Effect”.

The EKMM401VSN221MA25S has a large capacitance of 2300uF and a voltage rating of 30V. Its low equivalent series resistance (ESR) and maximum temperature rise of 65°C allows it to withstand high current and temperature. Due to its combination of capacitance, ESR, and voltage ratings, it is well-suited for use in high current applications such as power supplies.

Conclusion

The EKMM401VSN221MA25S is a high-performance aluminum electrolytic capacitor that is ideal for high-current applications. Its combination of capacitance, ESR, and voltage ratings make it well-suited for use in power supplies, power filter circuits, DC energy storage, DC-DC converters, frequency converters, and motor drives. Its low ESR and maximum temperature rise of 65°C, allows the capacitor to withstand high current and temperature, thus making it suitable for many applications.
