Wet Tantalum Capacitors
Gelled-Electrolyte Sintered Anode TANTALEX Capacitors Hermetically-Sealed with True
Glass-to-Tantalum Seal
FEATURES
Improved reliability through the use of a glass-to-tantalum
true hermetic anode seal is the prime feature of the Type
138D gelled-electrolyte sintered anode TANTALEX capaci-
tor. This construction eliminates all internal lead welds
while retaining the strength of internal lead-welded parts.
Additionally, this construction offers outstanding resistance
to thermal shock.
The military equivalent to the 138D is the CLR65 and
CLR69 which are qualified to MIL-C-39006/9 and /21.
Capacitors in accordance with military specifications
