TEMPERATURE COEFFICIENT OF RESISTANCE
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 of
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
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
coeffecient 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.
Example: Assume the operating characteristics demand a
temperature range from - 55 °C to + 125 °C. This requires a
± 35 °C Δ below - 20 °C and a ± 40 °C Δ above + 85 °C. The
extreme Δ 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.
