INTRODUCTION

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.

FEATURES

 QPL product with established reliability (ER): meets

requirements of MIL-PRF-55182/9

 Temperature coefficient of resistance (TCR): ± 2 ppm/°C max.

(- 55 °C to + 175 °C)

 Resistance tolerance: to ± 0.005 %

 Thermal EMF: < 0.1 µV/°C

 Qualified resistance range: 4.99  to 121 k (RNC90Y)

30.1

 to 121 k(RNC90Z)

 Specially conditioned non-QPL resistors available

See data sheet “Improved Performance Tested”

 Fast thermal stabilization

 Rise time: 1 ns without ringing

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.
