Edge Coupled Trace Inductance Calculator

Edge Coupled Trace Inductance Calculator

Estimate the inductance using: $$ L = \frac{\mu_0 \, l}{\pi} \ln\!\left(\frac{2(s+w)}{w}\right) $$

* Enter the overlapping trace length \(l\), trace width \(w\), and spacing \(s\) in millimeters (mm). They will be converted to meters, and the result is in microhenries (µH).

Step 1: Enter Parameters

e.g., 50 mm

e.g., 2 mm

e.g., 1 mm

Formula: $$ L = \frac{\mu_0 \, l}{\pi} \ln\!\left(\frac{2(s+w)}{w}\right) $$
where \(l\), \(w\), and \(s\) are in meters and \(\mu_0 = 4\pi \times 10^{-7}\) H/m.
