capacitor

Tantalum capacitors are a subtype of electrolytic capacitors. They are made of tantalum metal which acts as an anode, covered by a layer of oxide which acts as the dielectric, surrounded by a conductive cathode. The use of tantalum allows for a very thin dielectric layer. This results in a higher capacitance value per volume, superior frequency characteristics compared to many other types of capacitors and excellent stability over time. 

68uF 400V Electrolytic Capacitor is a high quality electrolytic capacitor which offers long life and high reliability. Electrolytic Capacitors are most commonly used type of capacitors in Electronic Circuits.
