Aluminum electrolytic capacitors are dynamic electronic components that handle transient current, accumulate charge, and provide an instantaneous source of energy. As such, they are widely used across a range of applications that require values of capacitance from the sub-microfarad (~0.1µF) to thousands of farads (~from 1,000µF). In this article we explore the specific application-and-working-principle of one such component, the EKZN500ELL270ME11D.

Working Principles of the EKZN500ELL270ME11D

The working principle of the EKZN500ELL270ME11D is relatively simple. The internal components of the capacitor consist of a stable aluminum foil, an ionically-conductive electrolyte, and a porous aluminum oxide (oxide) separator. When the capacitor is charged, the positive ions in the electrolyte migrate through the porous oxide to the foil, and an electrostatic charge is established between the two electrodes. This charge is what gives the capacitor its capacitance; thus, the capacitance of the component depends on the total area of the two electrodes, the distance between them, the electrolyte material, and the dielectric constant of the oxide separator. To discharge the capacitor, the charge is simply reversed by switching the applied voltage.
