Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are devices that store electrical energy using two metal plates separated by a dielectric, which is an insulating medium. These capacitors are the most common type of capacitor used in a variety of applications. They are used in everything from simple electronic circuits to microprocessors. The E81D401VSD102MA80W Aluminum Electrolytic Capacitor is a low-leakage device that is designed to meet the demands of high-power systems and is designed to operate at temperatures up to 105°C with a voltage rating of 450VDC.

How do Aluminum Electrolytic Capacitors Work?

Aluminum electrolytic capacitors are unique in their construction. They have an anode consisting of a typically round, aluminum foil sheet that is treated to increase its surface area. This sheet is then rolled up in a cylindrical shape, separated by a dielectric material, and the assembly is then sealed in a container. When an alternating or a direct current is applied, an oxidizing reaction occurs at the anode that increases the surface area of the aluminum. This increase in surface area provides increased capacitance.

Application Field and Working Principle of the E81D401VSD102MA80W

The E81D401VSD102MA80W Aluminum Electrolytic Capacitor is primarily used in power supplies, power converters, automotive electronic systems, and other high-power applications. This device offers high capacitance and low leakage, allowing for effective operation in high-power systems. The working principle of the E81D401VSD102MA80W is the same as that of all other aluminum electrolytic capacitors. An alternating or a direct current is applied, causing an oxidizing reaction at the anode which increases its surface area, thus increasing its capacitance.

Advantages of an Aluminum Electrolytic Capacitor

Aluminum electrolytic capacitors offer many advantages over other types of capacitors. They have higher capacitance per unit volume than most other capacitors and offer robust performance in a variety of applications. They are also relatively inexpensive, making them a cost-effective choice for many applications. Furthermore, aluminum electrolytics are available in a wide range of shapes and sizes, allowing them to be easily integrated into any design.
