TCR Calculator
Calculate how resistance changes with temperature using the Temperature Coefficient of Resistance.
Adjust inputs and the results update automatically.
Inputs
Enter data into the fields below
Initial Resistance
TCR Specification
Temperature Range
Formula
Linear first-order temperature model.
R(T) = R₀ × [ 1 + TCR × 10⁻⁶ × (T − T₀) ]
Valid for moderate temperature deltas where TCR can be treated as constant. For wide ranges or non-linear devices, use a piecewise or higher-order model.
Results
Resistance Change (ΔR)
+60.000 Ω
Percent Change
+0.600%
Final Resistance
10.060 kΩ
Over ΔT = 60.0 °C
