When the tables/graphs below are used together they show that when the parts are run at higher power ratings, the parts will run hotter, which has the potential of causing the resistance of the parts to shift more over the life of the part.

If the same resistor was instead run at 1/4 W in a 70 °C environment, the element will heat up to about 30 °C over ambient, and over the life of the part the resistance value could shift roughly ± 0.5 %. And if the resistor was run at its maximum power rating of 1/2 W in a 70 °C environment, it will heat up to about 61°C over ambient, and you could see the resistance value shift roughly ± 1 % over the life of the part. TEMPERATURE COEFFICIENT OF RESISTANCE ppm/°C ADDITION TO BASE TC IN THE EXPANDED PORTION OF THE TEMPERATURE RANGE Temperature coefficient (TC) of resistance is normally stated as the maximum amount of resistance change from the original + 25 °C value as the ambient temperature increases or decreases. This is most commonly expressed in parts per million per degree centigrade (ppm/°C). The resistance curve over the operating temperature range is usually a non-linear curve within predictable maximum limits. PTF resistors have a very unifom resistance temperature characteristic when measured over the operating range of - 20 °C to + 85 °C. The standard temperature coefficients available are X = ± 15 ppm/°C, Y = ± 10 ppm/°C and Z = ± 5 ppm/°C. Some applications of the PTF require operation beyond the specifications of - 20 °C to + 85 °C. The change in temperature coefficient of resistance is very small (less than ± 0.05 ppm/°C) over the expanded temperature range of - 55 °C to + 150 °C. Therefore, when operating outside the range - 20 °C to + 85 °C, the designer can plan for a worst case addition of ± 0.05 ppm/°C for each degree centigrade beyond either - 20 °C or + 85 °C as indicated in the graph. This applies to all three temperature coefficient codes. 4 3 2 1 - 20 °C TO + 85 °C BASE TC LIMIT 0 - 50 - 40 - 30 - 20 EXPANDED OPERATING RANGE - 55 °C TO - 20 °C 90 100 110 120 130 140 150 X, Y or Z EXPANDED OPERATING RANGE - 85 °C TO + 150 ° C Example: Assume the operating characteristics demand a temperature range from - 55 °C to + 125 °C. This requires a ± 35 °C below - 20 °C and a ± 40 °C above + 85 °C. The extreme being ± 40 °C means that the worst case addition to the specified TC limit of ± 0.05 ppm/°C times ± 40 °C or ± 2 ppm/°C. Therefore, a Z which is characterized by a base TC limit of ± 5 ppm/°C over the temperature range of - 20 °C to + 85 °C will exhibit a maximum temperature coefficient of ± 7 ppm/°C over the expanded portion of the temperature range of - 55 °C to + 125 °C.
