FEATURES
Improved reliability through the use of a glass-to-tantalum
true hermetic anode seal is the prime feature of the Type
138D sintered anode T
ANTALEX
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) 6WVDC Units: + 10% to - 25% of initial measurement.
b) 8WVDC and 10WVDC Units: + 10% to - 20% of initial
measurement.
c) 15WVDC Units: + 10% to - 15% of initial measurement.
d) 20WVDC and above:
10% of initial measurement.
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 120Hz, + 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
hour life test at a temperature of + 85
C or + 125
C at the
applicable rated DC working voltage.

This is expressed in volts.
To complete the three-digit
block, zeros precede the
voltage rating. A decimal

(6R3 = 6.3 volts).
See Ratings

0 = No outer tube.
2 = Outer plastic-film insulation.
Packaging:
The use of formed plastic trays for packaging these axial lead components is standard. Tape and reel is not recommended
due to the unit weight.
