INTRODUCTION
The RNC90Y has been the benchmark for high precision
established reliability discrete resistors since 1982. In 2000,
Vishay achieved a technological breakthrough with the
introduction of the commercial ultra precision low TCR Z201
resistor. This breakthrough has now allowed Vishay to
introduce an established reliability “R” level very low TCR
resistor. The RNC90Z TCR limit of ± 2 ppm/°C over the
extended range of - 55 °C to + 175 °C is a significant
improvement over the existing RNC90Y specification.
The RNC90Z is a direct replacement for the RNC90Y.

The response of military and non military grade resistors to environmental stresses can be made better by “Improved
Performance Testing” (IPT). The IPT part will see burn-in and cycling that removes the “knee” from the normal drift of non IPT
parts. (See Table 6 for the improvement to expect in military parts when calling for Vishay recommended screening). Users
should be aware that IPT testing renders the part non QPL and so a 3XXXXX part number will be assigned by Vishay. Consult
Applications Engineering for details and ordering advice.
