<sod>A '''tantalum electrolytic capacitor''', a member of the family of [[electrolytic capacitor]]s,  is a polarized [[capacitor]] whose [[anode]] [[electrode]] (+) is made of [[tantalum]] on which a very thin insulating [[oxide]] layer is formed, which acts as the [[dielectric]] of the capacitor. A solid or liquid [[electrolyte]] which covers the surface of the oxide layer serves as the second, [[cathode]], electrode (−) of the capacitor. Because of its very thin and relatively high [[permittivity]] dielectric layer, the tantalum capacitor distinguishes itself from other conventional and electrolytic capacitors in having high [[capacitance]] per volume (high volumetric efficiency) and lower weight.<eod>
