Aluminum electrolytic capacitors are a type of capacitors with an electrolyte, typically a liquid or a paste, between two conductive electrodes. Commonly used in power supplies, audio applications as well as signal conditioning, they are able to maintain a consistently high charge for more than a thousand times higher than typical ceramic capacitors. The EKMH201VNN471MQ30W is a type of aluminum electrolytic capacitor used for the same purposes.

The EKMH201VNN471MQ30W is a radial-leaded, low-impedance aluminum electrolytic capacitor. It features a maximum voltage rating of 200 Volts, a capacitance of 470μF to 1000μF, and a temperature coefficient of ±20%. The working temperature range of this capacitor is -40℃ to 105℃. The capacitance tolerance is ±20%, and the ripple current is 400mAmps at 105°C. It is an aluminum electrolytic capacitor with a long life of 2000 to 3000 hours and is a popular choice for many power-supply designs.

The EKMH201VNN471MQ30W aluminum electrolytic capacitor is mainly used in power supplies for automotive, audio, and other electro-mechanical applications. It also finds use in the filtering of high-frequency noise signals on printed circuit boards, AC adapters, and signal conditioning circuits. The capacitor’s low-impedance characteristics enable more efficient filter in response to transients spikes and ensures long life and stability in the application. Because of its robust construction, it can withstand high vibration levels. The EKMH201VNN471MQ30W also has an increased tolerance to rapid charging and discharging, making it suitable for intelligent electronics, telecommunications, and LED lighting.

The working principle of the EKMH201VNN471MQ30W aluminum electrolytic capacitor is based on Faraday\'s law of electrolysis. A non-conductive aluminum oxide insulator layer is formed on a pure aluminum foil, and the liquid electrolyte is then added to the system. The aluminum oxide acts as a dielectric layer, storing electric charge, and the electrolyte serving to maintain the polar oxide layer. Electrical connections are made to the two aluminum foil electrodes for circuit connection. When a direct current is applied to the capacitor, the aluminum forms an electrochemical cell, which stores the electric charge. When the capacitor is discharged, the charge is released from the aluminum oxide layer, and the EKMH201VNN471MQ30W is effectively able to perform its role as a filter or signal attenuator.

In summary, EKMH201VNN471MQ30W aluminum electrolytic capacitors are used in many different applications including power supplies, audio, signal conditioning, filtering, and vibration dampening. Its low-impedance characteristics allow it to act as a filter and attenuator in the circuit. Electrical connections are made to two aluminum foil electrodes, and a direct current is applied to the capacitor to charge it. The aluminum oxide acts as a dielectric, thereby storing electric charge. When the capacitor is discharged, the charge is released from the aluminum oxide layer, allowing the capacitor to perform its role as a filter or signal attenuator.
