Microstrip Trace Resistance Calculator

This calculator determines the resistance of a microstrip trace using the formula:

\[ R = \rho \cdot \frac{L}{T \cdot W} \cdot \left[ 1 + \alpha \cdot (\text{temp} - 25) \right] \]

Where:

\(\rho = \) resistivity

\(L = \) length

\(W = \) trace width

\(T = \) trace height

Note:

\(\rho_{\text{copper}} = 1.7 \times 10^{-6} \, \Omega \cdot \text{cm}\)

\(\alpha_{\text{copper}} = 3.9 \times 10^{-3} \, \Omega / \Omega / ^\circ\text{C}\)
