It can also be used to optimize efficiency, reduce noise, and recirculate current in switching power supply circuits.

Working Principle

The working principle of an aluminum electrolytic capacitor is based on the dielectric properties of a thin oxide film grown on the surface of the oxide-coated aluminum anode. The anode is immersed in an electrolyte solution made up of either salt water or an organic solvent. When voltage is applied across the capacitor, an electrical field is generated, which causes a current to flow between the anode and the electrolyte solution. As the current flows, oxygen ions from the electrolyte attach to the anode, forming an oxide film. This oxide film acts as the dielectric material, which stores the electrical charge that is passed between the anode and cathode.

The ELXV500ELL390MFB5D aluminum electrolytic capacitor has a low ESR value that is unaffected by temperature changes, meaning that it can handle continuous high-power applications with minimal power loss. It also features an ultra-low leakage current, ensuring that the capacitor can hold its charge for longer periods of time. Additionally, the ELXV500ELL390MFB5D capacitor is designed for high temperature operation, allowing for improved thermal performance.

In conclusion, the ELXV500ELL390MFB5D aluminum electrolytic capacitor can be used in a wide variety of applications requiring high reliability and long operating life. Its low ESR values, high temperature endurance, and ultra-low leakage current make it an ideal choice for applications such as power supplies, telecommunications, automotive electronics, household appliances, industrial control, and medical equipment.
