In terms of TCR, the CMx series offers below 75ppm/K across the entire resistance range as well as load capacity being guaranteed, even when the temperature of the contact points is high. Users will also benefit from long-term stability, less than 1.0% from the original values for all sizes after 2,000 hours of operation.
