  • Tantalum capacitors with internal current-limiting means
    Patent number: 4375075
    Abstract: An improved solid-electrolyte tantalum capacitor for decreasing the danger of tantalum capacitors fires. An opening is provided in the external protection of the capacitor to allow the evacuation of the solder providing the contact between the cathode lead and the cathode when molten.
    Type: Grant

  • Encapsulating solid tantalum capacitors
    Patent number: 4235009
    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.
