Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used in a variety of applications. They generally consist of two metal foils, an electrolyte, and an aluminum oxide film. An electrical charge is applied to the foils resulting in the buildup of an electric field between them.

The particular model of the aluminum electrolytic capacitor, 400BXW120MEFR18X30, is specifically designed for industrial applications as they require a high capacity with low leakage. The aluminum electrolytic capacitor has a rated working voltage of 15 VDC and a capacitance of 120 µF, and it can handle a large working Pulse current of 300 A. Additionally, it provides a high ripple current life up to 6,000 hours. It has low ESR (Equivalent Series Resistance) and ESL (Equivalent Series Inductance) allowing it to perform efficiently in a variety of applications. It also has a low temperature coefficient that enables it to accurately maintain its capacitance level, even when operating in high temperatures.

The 400BXW120MEFR18X30 aluminum electrolytic capacitor is used in a variety of applications such as power supplies, power amplifiers, battery charging, motor drives, and more. Its combination of high capacity, low leakages, high pulse current, and low temperature coefficient makes it an ideal choice for these applications. Additionally, its protective sleeve and glass-filled high-temperature nylon housing provide a reliable means of protecting the component against mechanical and electrical shocks.

The working principle of the aluminum electrolytic capacitor relies on the presence of the aluminum oxide film, which acts as the dielectric. When an external voltage is applied to the capacitor, positive and negative charges accumulate on the two plates of the capacitor, forming an electric field. This electric field allows for current flow by either releasing the charge from the capacitor (discharge) or by absorbing the charge (charge). This charge and discharge cycle is what allows the capacitor to store and release energy.

Due to its high capacity, low leakage, high pulse current, and low temperature coefficient, the 400BXW120MEFR18X30 aluminum electrolytic capacitor is an excellent choice for a variety of applications. It is highly reliable and protected from mechanical and electrical shocks by its protective sleeve and glass-filled high-temperature nylon housing. Additionally, itsworking principle is based on the electric field generated by the aluminum oxide film, allowing it to store and release energy efficiently.
