FEATURES
• Terminations: standard tin/lead (SnPb),
100 % tin (RoHS compliant) available
• Improved reliability through the use of a
glass-to-tantalum true hermetic anode seal is
the prime feature of the Type 138D sintered
anode TANTALEX® capacitor. This construction
offers outstanding resistance to thermal shock.
• Model 138D is the commercial equivalents of Tansitor
styles WT, UWT, Mallory-NACC styles TLX, TXX and
Military styles CL66, CL67, CLR65, and CLR69, designed
to meet the performance requirements of Military
Specification MIL-PRF-39006/09/21. Capacitors in
accordance with military specifications should be ordered
by their military part numbers.
Following the life test:
1. DCL shall not exceed 125 % of the original requirement.
2. The ESR shall not exceed 200 % of the initial requirement.
3. Change in capacitance value shall not exceed the
percentages below.
a) 6 WVDC Units: + 10 % to - 25 % of initial measurement.
b) 8 WVDC and 10 WVDC Units: + 10 % to - 20 % of initial
measurement.
c) 15 WVDC Units: + 10 % to - 15 % of initial measurement.
d) 20 WVDC and above: ± 10 % of initial measurement.
