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.

T
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).
E
If the temperature coefficient of a resistor of
R
ppm/°C, its resistance will be:
If the temperature coefficient is specified as ≤200
ppm/°C the resistance will be within the shaded area
as shown in Fig. 1.
