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.
