ABSTRACT:
Powdered plastic encapsulation of solid tantalum capacitors is achieved through coating the capacitors between 150.degree. C. and 250.degree. C. while biasing the capacitors at direct voltage between 0.2 and 1 times the rated voltage. The plastic is cured in about 3 minutes. The capacity temperature derating and the reverse current temperature derating are reduced with respect to capacitors encapsulated unbiased at the same temperature.
