Wet Tantalum Capacitors Sintered Anode TANTALEX^® Capacitors
Hermetically-Sealed with True Glass-to-Tantalum Seal
PERFORMANCE CHARACTERISTICS
Operating Temperature: - 55 °C to + 85 °C and with voltage
derating to two-thirds the + 85 °C rating at + 125 °C. Use of
Type 138D capacitors for high temperature applications is
recommended.
Capacitance Tolerance: At 120 Hz, + 25 °C. ± 20 %
standard. ± 10 %, ± 5 % available as special.
DC Leakage Current (DCL Max.): At + 25 °C, + 85 °C and
+ 125 °C: Leakage current shall not exceed the values listed
in the Standard Ratings Tables.
Life Test: Capacitors are capable of withstanding a 2000 h
life test at a temperature of + 85 °C or + 125 °C at the
applicable rated DC working voltage.
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
Pb-free
Available
RoHS*
COMPLIANT
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.
