Working Principle

The working principle of ELBK350ELL842AM40S aluminum electrolytic capacitors is based on Faraday’s law of electrolysis: when an electrolyte is placed between two conductors, an electric current passes through the electrolyte, resulting in the production of electric charges on the surface of the two electrodes. This process is reversible, which enables the capacitor to store and transfer energy.

At the heart of ELBK350ELL842AM40S aluminum electrolytic capacitors are an anode (positive electrode) and a cathode (negative electrode) which are composed of highly conductive aluminum layers. When a voltage is applied across the two electrodes, a thin layer of non-conductive aluminum oxide is formed, allowing charge accumulation.

The capacitor is able to store and release energy cyclically, thereby providing huge amounts of peak power for a small amount of time, and smoothing out the ripple current.
