Aluminum electrolytic capacitors are electrochemical components widely used in power supply systems for energy storage, buffering, and power factor adjustment. The EKMQ401VSN391MA30W is a large-capacity model of these capacitors. This model can be used in a wide range of applications, including filtering, harmonic suppression, energy storage, DC link circuits, and motor start-up circuits.

The EKMQ401VSN391MA30W is designed with an anode made of aluminum foil, coated with an oxide insulating layer. This is separated from the cathode by electrolytes, such as conductive organic solvents, porous separators, and oil. The electrolyte acts as a medium for electrical conduction and allows ions to move freely between the anode and the cathode, generating a capacitance that can store energy. The capacitance of the EKMQ401VSN391MA30W is 40,000 μF and its rated power is up to 800 W.

The primary advantage of using aluminum electrolytic capacitors is their ability to store large amounts of energy over long periods of time. The EKMQ401VSN391MA30W offers a range of benefits, including high operating reliability, low internal resistance, good heat dissipation, and high capacitance stability. Additionally, its self-healing features help reduce the impact of short circuits and current overloads.

When using an aluminum electrolytic capacitor, it is important to consider the ambient temperature and frequency of operation. Depending on the operating temperature, the rated capacitance of an aluminum electrolytic capacitor can be reduced by up to 50%. Similarly, high-frequency operation can also reduce the capacitance of the device.

The EKMQ401VSN391MA30W also offers a wide temperature range, with its working temperature range stretching from -40°C to +105°C. This, in combination with its high dielectric strength and long lifetime, makes it an ideal choice for applications in which high-performance and reliability are paramount.

In summary, the EKMQ401VSN391MA30W is an excellent choice for a variety of applications. It offers a range of benefits, including high operating reliability, low internal resistance, good heat dissipation, high capacitance stability, and temperature and frequency resistance. Its wide temperature range makes it ideal for applications in which high performance and reliability are essential.
