HIGH PERFORMANCE WET TANTALUM CAPACITORS

The wet electrolytic tantalum capacitor was the first tantalum capacitor. It is in reality two electrochemical capacitors in series. It consists of a porous sintered tantalum anode, upon which has been grown a thin film of tantalum oxide (Ta2O5) which becomes the dielectric. The secondary capacitor plate is a combination of three materials.
