5. Not to exceed power rating of resistor.
2. Heat sink chassis dimensions and requirements per
MIL-PRF-39009:
6. µV/°C relates to EMF due to lead temperature difference and
µV/watt due to power applied to the resistor.
7. Vishay test data as compared to MIL-PRF-39009 is shown for
illustration purposes, Vishay test conditions that deviate from the
MIL test method are noted within parentheses.

exceed 750 V.
3. Inductance (L) due mainly to the leads.
4. The resolution limit of existing test equipment (within the
