Military Established Reliability
Vishay Foil Resistors
Bulk Metal® Foil Technology
RNC90Y and RNC90Z to MIL-PRF-55182/9
FEATURES
• QPL product with established reliability.
• Best Load Life Stability: ± 0.05%∆R for 2,000 hrs. @ + 125°C
Product may not
be to scale
• Best TCR: ± 2.0ppm/°C (– 55°C to + 175°C)
• Best Shelf Life: 0.0025% (25ppm) for 1 year
• Best Thermal EMF: 0.1µV/°C
Vishay Military Established Reliability resistors are available
in resistance values from 4.99 ohms through 121Kohms 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.
• Qualified Resistance Range: 4.99 Ω to 121KΩ [RNC90Y]
100 Ω to 121KΩ [RNC90Z]
• Resistance Tolerance: to ± 0.005%
• Specially conditioned non-QPL resistors available.
See data sheet “Improved Performence Tested.”

NOTES:
1. Maximum TCR spread from nominal (Vishay maximum TCR): spread is defined as the 3σ (99.73% of a production lot) limit of a nominal
Gaussian distribution which is within a band centered on the nominal curve. TCR is somewhat higher for resistance values < 80ohms,
consult Vishay Applications Engineering.
2. Load life ∆R Maximum can be reduced by 80% through a screening procedure. 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/watt due to power applied to the resistor.
6. Maximum is 1.0% A.Q.L. standard for all specifications except TCR. Typical is a designers reference which represents that 85% of the
units supplied, over a long period of time, will be at least the figure shown or better.
