Aluminum electrolytic capacitors are widely used in a variety of electrical and electronic devices. The ETXH401VSN271MR40S is one of the most popular types in this category. It is a radial leaded, long-life, mid-voltage aluminum electrolytic capacitor with a low profile that is suitable for many applications such as SMPS, AC/DC adapters and DC/DC converters.

This aluminum electrolytic capacitor is a non-polarized device with a rated voltage of 16V, which means it can safely handle up to 16V. It features a wide capacitance range from 1.0 µF to 220 µF and is available with various capacitance tolerances of ± 20%, ± 10%, ± 5% and ± 2%. The operating temperature range of this capacitor is -40 °C to +105 °C. It also has a long service life of 2000 hours at an operating temperature of 105 °C.

This aluminum electrolytic capacitor utilizes a double-sided layer of aluminum foil as two electrodes with electrolyte between the electrodes. The anode is in contact with the electrolyte while the cathode is separated with impregnation paper. When a direct current is applied, the electrolyte creates an electric field around the anode, causing the surface of the anode to form a very thin oxide layer. This oxide layer works as an insulator to increase the capacitance between the anode and cathode. The capacitance created by this layer is proportional to the surface area of the electrodes and the distance between them, as well as the dielectric constant of the electrolyte.

ETXH401VSN271MR40S aluminum electrolytic capacitor is commonly used in power supplies, detection and circuit protection, electric audio systems, frequency converters, signal couplers, power amplifiers, medical electronics, and many other applications. The aluminum electrolytic capacitor provides low leakage current, low dissipation factor, good frequency characteristics, and high ripple current capabilities. It also has good stability and reliability.

In conclusion, the ETXH401VSN271MR40S aluminum electrolytic capacitor is a popular product in this category due to its wide capacitance range, long service life, good stability and reliability. This capacitor is typically used in power supplies, detection and circuit protection, audio systems, signal coupling, and many other applications. The working principle of this capacitor is based on the formation of an oxide layer between the anode and cathode which creates a capacitance between the electrodes.
