Aluminum electrolytic capacitors are polarized capacitors whose anode electrode is made of a pure aluminum foil with an etched surface. A paper separator impregnated with an ionic conductor serves as the dielectric, and a liquid or solid electrolyte serves as the cathode. The capacitor\'s small size and low cost make it suitable for many applications. ESMM501VND391MA50T is a type of aluminum electrolytic capacitor that is a small, general purpose capacitor with a long life expectancy. A brief understanding of its applications and its working principles can help you choose the right capacitor for your needs.

Applications

The ESMM501VND391MA50T is suitable for a range of applications, including motor run, energy-efficient equipment, power amplifiers, and LED lighting. Thanks to its small size and high-capacity, this capacitor is often used in DC-DC converters and inlays. Other types of aluminum electrolytic capacitors are popular in electrical appliances, telecommunications, computers, and consumer electronics.

Working Principle

Aluminum electrolytic capacitors operate on the principle of electrolyte being released when voltage is applied to the anode and cathode. As the electric voltage applied to the anode exceeds that of the cathode, oxygen ions in the electrolyte (usually a liquid) are released to the negative electrode. The positive ions combine with the aluminum atoms of the positive electrode to form an oxide layer, increasing the dielectric strength of the capacitance structure. This process is rapid and reversible, allowing the capacitor to endure a long life expectancy.

For the ESMM501VND391MA50T, the dielectric is composed of a moist paper layer and a solid of aluminum oxide. It also features a one-direction part type that prevents reverse leakage current and increases its efficiency. Compared to other electrolytic capacitors, it has a much higher capacity and stability.

Features

The ESMM501VND391MA50T is a radial leaded, asymmetric, aluminum electrolytic capacitor that features a stable capacitance and superior endurance. It has several features that make it a reliable general purpose option, including:

• High temperature range: -40°C to +105°C
• High voltage rating: 163V to 450V
• High capacitance: 31.000uF to 50.000uF
