INTRODUCTION
Vishay Military Established Reliability resistors are available
in resistance values from 4.99 Ω through 121 kΩ and for
tolerances from ± 0.005 % to ± 1.0 %. The same resistors are
also available as a non-qualified product for customers
desiring higher or lower resistance values and the same or
better performance capabilities. (See table 2) Both the
qualified and the non-qualified version are manufactured on
the same production line facilities and are subjected to the
same process, lot control, conditioning, and GRP A (100 %)
screening. Qualified versions receive additional MIL Group B
and C testing.

The response of military and non military grade resistors to environmental stresses can be made better by “Improved
Performance Testing” (IPT). The IPT part will see burn-in and cycling that removes the “knee” from the normal drift of non IPT
parts. (See Table 4 for the improvement to expect in military parts when calling for Vishay recommended screening). Users
should be aware that IPT testing renders the part non QPL and so a 3XXXXX part number will be assigned by Vishay. Consult
Applications Engineering for details and ordering advice.
