temperature coefficient of resistance [TCR(T_ref)]

The fractional change in resistance of the test structure per unit change in temperature at a specified temperature T_ref, as described in the following equation:

where

R(T_ref) is the resistance of the test structure at temperature T_ref (Ω);
ΔR is the change in resistance (Ω);
ΔT is the change in temperature that caused the change in resistance (°C).
