“R” level high reliability resistor qualified to MIL-PRF-55182/9
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
resistor. The RNC90Z TCR limit of
“
R
”
level very low TCR
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.
