Reverse Bias Behavior of Surface Mount Solid Tantalum …
The probability of failures of incorrectly installed solid tantalum capacitors has long been an issue in the aerospace community. G. J. Ewell from The Aerospace Corporation addressed this issue in 1984 by analyzing behavior of hermetically sealed metal case solid tantalum capacitors under reverse bias conditions [1].

Tantalum Capacitor:Construction,Characteristics, 5 Uses
A tantalum capacitor is one kind of electrolytic capacitor, which is a passive electrical device. It uses a capsule of spongy tantalum metal as an anode. An insulating layer of oxide covers the anode. The oxide layer further generates the dielectric. It is surrounded by a solid or non-solid electrolyte, which serves as a cathode.
