Tantalum capacitor

A tantalum electrolytic capacitor is an electrolytic capacitor, a passive component of electronic circuits. It consists of a pellet of porous tantalum metal as an anode, covered by an insulating oxide layer that forms the dielectric, surrounded by liquid or solid electrolyte as a cathode.

TECHNICAL PAPER

Tantalum capacitors are capacitors constructed with tantalum material used to form the anode of the capacitor. Tantalum capacitors are electrolytic capacitors, which means the capacitor is formed by an oxide layer formed on the anode and is thus polarized. A tantalum capacitor includes a tantalum powder anode, a Ta5 oxide layer 2O

The reliability of a component is a property that indicates how well a component performs its function in a time interval. It is subject to a stochastic process and can be described qualitatively and quantitatively; it is not directly measurable. The reliability of electrolytic capacitors are empirically determined by identifying the failure rate in production-accompanying endurance tests, see Reliability engineering#Reliability testing
