Military and Space Established Reliability

Vishay Foil Resistors

RNC90Y and RNC90Z (Z-Foil) to MIL-PRF-55182/9

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.

FEATURES

• QPL product with established reliability (ER): meets

requirements of MIL-PRF-55182/9

• Load life stability: ± 0.005 % for 2000 h, 0.3 W at + 125 °C

• 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 Ω to 121 kΩ (RNC90Y)

30.1

Ω to 121 kΩ (RNC90Z)

• 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.
