Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are capacitor types, using a solid aluminum oxide or metal film as an ionic conductive medium. They are predominantly used for power applications and decoupling applications. These capacitors are characteristically large, and are made with a cylindrical anode or cathode that is rolled into layer. The anode and cathode contacts are connected by the electrolyte that was deposited on the metal oxide layer. These capacitors have higher capacitance and potential in comparison to other capacitors. This makes them ideal for industrial and electrical applications.

ESMH401VND471MB30T application field and working principle

The ESMH401VND471MB30T is a type of aluminium electrolytic capacitor. It has a capacitance of 4.7 uF, a voltage rating of 400 VAC, a diameter of 11.7 mm, and a height of 12.7 mm.The capacitor is suitable for applications that require high-power and high-voltage handling, such as power supplies, voltage regulators, and power amplifiers. The capacitor is able to store and transfer electrical energy by the principle of two conductive surfaces separated by a dielectric. It is a polarized capacitor, which means that the anode must always be at higher potential than the cathode. Its ability to handle high-power makes it suitable for high-power applications.

The ESMH401VND471MB30T is constructed with an anode and a cathode, separated by an electrolyte. The anode and cathode are made of aluminium foil, while the electrolyte consists of an electrolytic solution (or liquid) of aluminium oxide. The walls of the capacitor are filled with gas to ensure a long lifetime. When an external voltage is applied across the anode and cathode, the electric field causes the aluminum oxide to break apart into ions, forming an electrical double layer. This micro-droplet or double layer stores electric charge, allowing it to function as a capacitor.

The ESMH401VND471MB30T is capable of handling high-power due to its extremely high efficiency. It has an extremely low equivalent series resistance (ESR) due to the enabling of electrical currents by the electrolyte. This results in less power dissipation and the ability of the capacitor to handle high current. The low ESR also increases the capacitor\'s reliability and lifespan.

The ESMH401VND471MB30T is manufactured to have a long lifetime, and can have an operating temperature range between -55 degrees Celsius to 105 degrees Celsius. The capacitor is also able to retain its original characteristics even when the temperature is changed.

The ESMH401VND471MB30T can be used for numerous applications, such as filtering, coupling, decoupling, and bypassing. It can also be used in applications that require high surge, high ripple, and high-power performance. This all-rounded capacitor is suitable for a variety of industrial and electrical applications.
