Working Principle of ESMG250ELL472MN25S

Aluminum electrolytic capacitors are constructed by sandwiching a porous anode between two electrolyte-soaked separator sheets. This anode is traditionally made from an aluminum foil that is etched with a pattern to increase the surface area of the anode. The porous anode creates an even distribution of polymer developed in the electrolyte, which in turn increases the capacitance of the capacitor. During operation, a potential difference, referred to as the applied voltage, is created between the anode and the electrolyte on the other side of the separator. This potential difference is responsible for the electrochemical reaction of the capacitor, where electrons are exchanged between the anode and the high-purity electrolyte.

The voltage is determined by the amount of electrons stored, and the total amount of electrons stored is determined by the utilized electrolyte and anode material. The high density of the created electrolyte helps reduce the equivalent series resistance (ESR) of the capacitor. This reduction ultimately helps reduce the amount of heat generated, increases the life of the capacitor, and ultimately increases its efficiency.
