•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
• Qualified Resistance Range: 4.99 Ω to 121KΩ [RNC90Y]

• 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.
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.

Please specify Vishay RNC90Y and RNC90Z Series Resistors as follows: (See Table 2, 4 and 5 for further details.)
Resistance value, in ohms, is expressed by a series of 6 characters, 5 of which represent significant digits while the 6th is a dual
purpose letter that designates both the multiplier and the location of the decimal point.
For Military approved resistors with improved performance testing a unique 3XXXXX part number will be assigned.
