Tantalum Capacitors Review
A tantalum capacitor is comprised of a permeable tantalum center section surrounded by tantalum pentoxide. A tantalum wire is inserted into the center section and then extends axially from the component. The tantalum pentoxide layer is coated with manganese dioxide, graphite, a silver conductive coating and (finally) solder.

Basics of tantalum electrolytic capacitors
Tantalum capacitors are one of the three types of electrolytics. The others are aluminum and niobium. All electrolytics are polarized devices whose anode (+) acquires an insulating oxide layer when voltage is first applied. This dielectric layer is quite thin, a characteristic that makes for high capacitance in a small package.

The process is repeated until a thick coating is present on all internal and external surfaces of the pellet. Finally, the pellet used in solid tantalum capacitors is dipped into graphite and silver to provide a good cathode connection. In contrast to solid tantalum capacitors, wet tantalum capacitors use a liquid electrolyte.
