Working Principle

Tantalum capacitors are constructed with an anode made of sintered tantalum powder, an electrolyte made of manganese dioxide, and anodes connected to two internal electrodes. The anode is formed by sintering a tantalum oxide powder which has been compacted along with a catalytic metal and, in some cases, carbon powder. The electrolyte acts to ionize the tantalum anode so that an electrical charge can be stored. The two internal electrodes provide an electrical contact to the tantalum anode and allow capacitors to be connected in parallel with other components in a system. The anode and the electrolyte form a dielectric layer that holds the charge. The charge is held in the dielectric layer and released when the applied voltage is greater than the breakdown voltage across the dielectric..
