The working principle behind the MAL216352221E3 aluminum electrolytic capacitor is that when a voltage is applied across it, electrons flow through the dielectric oxide layer and create an electrostatic field that stores energy. The amount of capacitance is determined by the thickness of the oxide layer, its surface area, and its dielectric constant. The electrolyte is necessary to maintain the breakdown voltage and capacitance. As the capacitor is used, the electrolyte is gradually adsorbed into the oxide layer which increases the capacitance and maintains the breakdown voltage.
