Military Established Reliability resistors from Vishay Foil
Resistors are available in resistance values from 4.99
through 121 k 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 R Maximum can be reduced by 80 % through Enhanced Reliability Testing (ERT). Consult our 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.
