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 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.
