Evaluation of wet tantalum capacitors after exposure to extended periods of ripple current, volume 2 [PDF]

The application of tantalum capacitors in the Viking Lander includes dc voltage and ripple current electrical stress, high temperature during nonoperating times (sterilization), and high vibration and shock loads. The capacitors must survive these severe
