INTRODUCTION

to 121 k
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.
•
Specially conditioned non-QPL resistors available
See data sheet “Improved Performance Tested”
Fast thermal stabilization

•
Rise time: 1 ns without ringing
Special coatings that provide a cushioning layer which isolates
the resistive element from external stresses and moisture
Electrostatic discharge (ESD) above 25 000 V
Non inductive, non capacitive design
Current noise < - 42 dB
Prototype sample available from 72 h

Notes
1. Qualification and failure rate verification test data is maintained by Vishay Foil and is available upon request. Lot traceability and identification
data is maintained by Vishay Foil for 7 years.
2. Load life ΔR Maximum can be reduced by 80 % through Enhanced Reliability Testing (ERT). Consult Vishay Applications Engineering for
details.
3. Inductance (L) due mainly to the leads.
4. Not to exceed power rating of resistor.
5. µV/°C relates to EMF due to lead temperature differences and µV/W due to power applied to the resistor.
6. 0.200" (5.08 mm) lead spacing available - specify RNC90T for RNC90Y, and RNC90S for RNC90Z.
