Construction and Working Principle

The construction of this type of capacitor comprises of a foil electrolyte, with two layers of plain aluminum foil, being separated by an electrolytic-layer. The aluminum foil and electrolyte combine to form the electrical double-layer that stores charge. This electrical double-layer is what gives these capacitors their unique characteristics.

The working principle of the LNT2W221MSEC capacitor is based on the electrical double-layer formed by the metal foil and the electrolyte layer. When a voltage is applied, charge moves from the metal foil to the electrolyte layer, forming an electrical double-layer on the metal foil. This electrical double-layer stores the electrical charge, and is what enables the capacitor to store energy.
