Tantalum Capacitors

Tantalum capacitors have three components, a pellet of tantalum metal that acts as an anode, an insulating oxide layer that constitute a dielectric, which is surrounded by conductive material that acts as a cathode. Owing to low ESR, high operating temperature and low leakage, tantalum electrolytic capacitors are used in sample and hold circuits as well as in some time circuits. Future Electronics offers them in varied types, including conformal coated, polymer, solid leaded, and solid SMD tantalum capacitors to choose from.
