Working Principle

An aluminum electrolytic capacitor works on the principle of electrostatic coupling. This is the phenomenon of electrons from a conductive material (usually aluminum) being attracted to and repelling each other in response to an electrical field. The capacitor consists of an anode and a cathode separated by a dielectric material, usually an electrolyte. The electrolyte and the space between the two plates form the capacitor\'s dielectric, which is responsible for storing the capacitor\'s charge.

The EPAG401ELL121MM30S aluminum electrolytic capacitor utilizes the electrolytic process, which consists of two reservoirs of conducting electrolytes, connected together by a thin membrane. The thin membrane selectively passes protons, allowing electrons to flow from one solution to the other. In the presence of an electric field, this creates a potential difference between the two reservoirs, which is stored in the form of electric charge on each of the plates, forming a capacitor.

The EPAG401ELL121MM30S aluminum electrolytic capacitor is designed to meet specifications for reliable and consistent performance in a variety of applications. The capacitor is constructed with aluminum foil electrodes and a conductive polymer electrolyte, which makes it rugged and reliable. In addition, the capacitance of the EPAG401ELL121MM30S is highly stable over time, making it ideal for applications such as bypassing the power supply and filtering noise in analog circuit designs.
