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:
鹵
10% of initial measurement.
