Microstrip Inductor Calculator

Estimate the inductance using: $$L=\frac{{\mu }_0{N}^2{d}_{\text{avg}}}{2}[\ln \left(\frac{2.46}{\rho }\right)+0.2{\rho }^2]$$

* Enter the number of turns $N$, inner diameter $d_{\text{in}}$ (mm), and outer diameter $d_{\text{out}}$ (mm). Diameters are converted to meters, and the result is given in nanohenries (nH).
