ADDITIONAL TESTING TO MIL SPEC
Group A testing to MIL-PRF-83401 imposes the following:
1. Thermal shock 100%
5X from – 65 to + 125C.
2. Power conditioning 100%
2. 1 100 hours at 25C, full power.
2. 2 ∆R and ∆ ratio calculation.
3. Visual and Mechanical after the above tests (sample plan)
3. 1 Conformity to physical size.
3. 2 Workmanship
3. 3 Damage due to the above tests.
4. 10% PDA or one piece whichever is greater.
5. Solderability (sample plan).
Group B sample testing to MIL-PRF-83401 imposes the following:
1. Temperature Coefficient of Resistance (sample plan).
2. Resistance to solvents (sample plan).
Vishay Models 1445Q and 1446Q networks are qualified to
MIL-PRF-83401, Characteristic C, Schematic A. Actual
performance exceeds all the requirements of MIL-PRF-83401
characteristics "C."
Model 1445Q contains 7 resistors and 1446Q contains 8 resistors.
Qualified resistance range is 100 ohms through 10Kohms. Other
values are available non-QPL. Power rating is 0.1 Watt.

TEST OR CONDITION
1. ∆R's are not cumulative. For purposes of determining reliability calculations, consider the characteristics shown as figures of merit and
allow no more than ± 0.05% ∆R lifetime. Allow proportionately less if the severity of anticipated environmental stress is small compared to
the tests as defined in MIL-PRF-83401.
