Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor consists of two aluminum foils with an insulating oxide layer, separated by a paper spacer. The two foils form the capacitor\'s plates and the paper spacer acts as the dielectric. The aluminum electrolytic capacitor is one of many types of capacitors and is typically smal, low-cost and widely used. HVMLS113M040EB1D aluminum electrolytic capacitors are one example of the many round, can shaped, splined, and other variations available on the market.

Application Field

The HVMLS113M040EB1DS aluminum electrolytic capacitors are used for a variety of applications, including power supplies, electrical and electronic equipment, computing equipment, communications systems, motor drives, and lighting systems. The advantage of these capacitors compared to other types of capacitors is their ability to store a higher amount of electric charge, which makes them ideal for applications that require high-frequency or high-power electrical components. These capacitors are also used in the automotive industry because of their stability, long life, and low cost.

Working Principle

The working principle of aluminum electrolytic capacitors is based on the fact that electric current is conducted through an ionized solution. When the capacitor is charged, an invisible layer of ions forms at the dielectric between the two plates, and these ions are attracted to the negative plate. This layer of ions forms a conducting path between the two plates, creating an electric field between them and thus allowing electrical current to pass between them. As the ions are pulled to the negative plate, negative charge builds up around the capacitor, which serves as a barrier to the electric current.

When the capacitor is discharged, the ions are repelled from the negative plate, and the electric current ceases to flow. The capacitor is now ready to be recharged again, and the process of ionization and discharging is repeated. This continuous cycle is what allows the capacitor to store and discharge electrical energy.

The HVMLS113M040EB1DS aluminum electrolytic capacitors have a large capacitance and therefore can store a significant amount of energy. These large capacitance capacitors are suitable for high power and high-frequency applications. They are also resistant to temperature changes and can handle up to 40°C without any damage.
