Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor is a capacitor that utilizes an electrolytic solution and an aluminum foil for its construction. It is constructed by coating the aluminum foil with an electrolyte, such as boric acid, and then sandwiching the foil between two layers of paper or plastic. This type of capacitor is referred to as a “floating electrode” capacitor because the charge in the capacitor is shared between the two plates, and the foil is not actually in direct contact with conductive medium.

The thesis associated with the application of this product is that by utilizing a liquid solution, a much higher capacitance can be achieved than is possible with a traditional electrolytic capacitor. The aluminum foil forms a barrier between the two surfaces of the capacitor, providing a relatively high capacitance when compared to a traditional capacitor.
