The temperature coefficient of resistance is a ratio
which indicates the rate of increase (decrease) of
resistance per degree (°C) increase (decrease) of
temperature within a specified range, and is
expressed in parts per million per °C (ppm/°C).

When specifying the performance of a resistor, the
dissipation is given as a function of the hot-spot
temperature, with the ambient temperature as a
parameter.
From ? T = A × P and T m = T amb ? ? T it follows
that:
P ?

If P is plotted against Tm for a constant value of A,
parallel straight lines are obtained for different
values of the ambient temperature. The slope of
these lines,
E XAMPLE
If the temperature coefficient of a resistor of
R nom = 1 k X between –55 °C and +155 °C is ±200
ppm/°C, its resistance will be:
at 25 °C:
1,000 X (nominal = rated value)
at +155 °C:
1,000 X ±(130 × 200 ppm/°C) × 1,000 X
= 1,026 X or 974 X
at –55 °C:
1,000 X ±(80 × 200 ppm/°C) × 1,000 X
= 1,016 X or 984 X
