Working principle of UVZ2E220MHD

Aluminum electrolytic capacitors involve two aluminum foils separated by a paper insulating material, with electrodes and a sealant material in between. The aluminum foil provides the low resistance path for current flow, allowing very large capacitance to be achieved in a very small size.

The base of the capacitor is filled with a highly conductive liquid electrolyte composed of an ionic solution and the sealant material helps the capacitor maintain its shape, pressure, and the sealant prevents moisture and other environmental elements from entering.

When a voltage is applied to the capacitor, the liquid electrolyte ionizes, creating a thin layer of ions that travels to the aluminum surfaces of the electrodes and provides conduction between them. This creates a capacitor, allowing current to flow between the two electrodes until it reaches the saturation current, after which the capacitor operates in DC mode.

An important feature of aluminum electrolytic capacitors is that the capacitance tolerance is relatively low, typically around ±10%. As capacitance increases, the tolerance decreases, with tolerance of ±5% achievable with large capacitance values.
