MIL-PRF-19500/478K
* 4.3.2 Thermal impedance. The thermal impedance measurements shall be performed in accordance with method
3101 or 4081 of MIL-STD-750 using the guidelines in that method for determining IM, IH, tH, tSW (VC and VH where
appropriate). Measurement delay time (tMD) = 70 µs max. See table II, subgroup 4 herein.
4.3.3 Burn-in. Burn-in conditions for all quality levels are as follows: method 1038 of MIL-STD-750, test condition
A, TC = +125°C; VR = 80 to 85 percent of rated VR dc (see 1.3).
4.4 Conformance inspection. Conformance inspection shall be in accordance with MIL-PRF-19500.
4.4.1 Group A inspection. Group A inspection shall be conducted in accordance with appendix E, table E-V of
* 4.4.2 Group B inspection. Group B inspection shall be conducted in accordance with the conditions specified for
subgroup testing in tables E-VIA (JANS) and E-VIB (JAN, JANTX, and JANTXV) of MIL-PRF-19500 and as follows.
Electrical measurements (end-points) shall be in accordance with table I, subgroup 2 and the applicable step and
footnotes of table III herein.
