Established Reliability (ER)
The RNC90Y established reliability resistor has been the benchmark for high precision established reliability discrete resistors since 1982. In 2000, we achieved a technological breakthrough with the introduction of the Z201 resistor with a TCR of 0.2 PPM/°C. This breakthrough has allowed Vishay Precision Group to introduce the RNC90Z established reliability “R” level resistor, with a TCR limit of ± 2ppm/°C over the extended range of - 55°C to + 175°C, this being a significant improvement over the existing RNC90Y’s ± 5ppm/°C TCR specification.
