Working Principle of EKMG401ELL470MLN3S

The principle of an aluminum electrolytic capacitor consists of three main details: a wet electrolyte, an anode foil, and a dielectric created on the anode foil. The anode foil consists of pure aluminum. A thin oxide layer is grown on the aluminum surface when exposed to oxygen in the air while the oxide layer thickens when exposed to electrolyte. The oxide will then malfunction if the environment of the capacitor is not good enough. Therefore, it is important to keep the environment of the aluminum electrolytic capacitor acceptable. The oxide layer is what acts as a dielectric for the capacitor.

The anode foil is then rolled into a cylinder and woven in a lattice structure and a separator is placed between them. The separator is usually composed of a special paper module or a polyester or polypropylene film with a designated funnel-entry. The electrolyte is placed between the cells with the specific gravity depending upon the working voltage. Finally, the cavity is sealed with a lid with a flexible seal material added to be protected from moisture and electrolyte conversion.
