Asymmetric Stripline Impedance

Asymmetric Stripline PCB Formula
Note: valid for (w/h) from 0.1 to 2.0 and (t/h) less than 0.25

Dimensional units: mm mils
w (trace width) =
t (trace thickness) =
h (smaller dielectric thickness) =
h1 (larger dielectric thickness) =
er (relative dielectric constant) =

Asymmetric Stripline

Zo (Impedance, Ohms) =
Note: 1oz = 1.4mils = 0.03556mm
