Aluminum electrolytic capacitors, also known as aluminum electrochemical capacitors, are components that store electric energy by establishing an electric field between the electrodes of the capacitor when the electrode is surrounded by electrolyte. The model EKMH401VNN121MQ30N is one such aluminum electrolytic capacitor.

These types of capacitors are characterized by relatively large capacitance values per unit volume. This makes them a popular choice for applications where large amounts of capacitance are needed in a small package. They also operate at low cost and are relatively easy to manufacture.

When compared to other types of capacitors, aluminum electrolytic capacitors have a much larger equivalent series resistance (ESR). This means that the resistance of the capacitor increases as the frequency increases. This is not usually a problem for most applications. As a result, aluminum electrolytic capacitors are often used in power supply filter circuits, pulse circuits, and voltage rectification circuits due to their ability to store large amounts of energy.

The EKMH401VNN121MQ30N aluminum electrolytic capacitor is a surface-mount component with an operating temperature range of -40°C to +125°C. It has an impedance of less than 0.0085 ohms at 100 kHz and a capacitance of 390uF. The operating voltage range for the capacitor is 35 volts to 100 volts.

The working principle of the EKMH401VNN121MQ30N capacitor is based upon the electrode setup and the electrolyte. The electric field between the capacitor’s two electrodes is formed when an alternating electric current is applied to the electrolyte. This causes protons and electrons to move from one electrode to the other, resulting in the buildup of charge. This charge can then be tapped and used by a device for energy storage.

Due to its high capacitance values, the EKMH401VNN121MQ30N capacitor is commonly used in power supplies, booster capacitors, and other high voltage circuits. It can also be used in switching power supplies, power amplifiers, and other electronic circuits that require high energy storage.

In summary, aluminum electrolytic capacitors, such as the EKMH401VNN121MQ30N, are widely used in electronic applications due to their high capacitance values and their ease of use. They are characterized by relatively large capacitance values per unit volume and high operating voltage grades, making them well suited for use in a variety of applications.
