The capacitor is composed of two layers of aluminum foil which are used as the electrodes, and a strip of paper soaked in an electrolytic solution which serves as the dielectric material. When a voltage is applied across the terminals of the capacitor, the electric field across the electrodes creates a current, which causes ions in the electrolyte to move and deposit on the surface of the electrode. This causes a buildup of opposite charges on each electrode, resulting in a capacitance being formed. Thus, the B41690A5208Q9 aluminum electrolytic capacitor operates on the principle of electrochemistry.
