Power Derating Curve
The power derating curve illustrates the relationship between terminal temperature and power ratio. The device can handle up to 100% power ratio at temperatures up to 125 C.
TCR Curves
Temperature Coefficient of Resistance (TCR) curves are provided for different resistance values and temperature ranges. For the 25 value, the TCR on test points is 100 ppm/C. For 50 and 100 values, it is 50 ppm/C. The TCR for the resistance alloy is < 50 ppm/C.
