Embedded Microstrip Impedance Calculator


Provide values for the four parameters h1, h, t, w, and the relative permittivity of the dielectric. Click the button corresponding to the characteristic impedance to calculate its value. ( 0.1< w/h < 3.0; 1 < εr < 15 )

Select the units for all dimensions: mm mils

h1 (Dielectric thickness)
mm mils
h (Height above reference plane)
mm mils
t (Trace thickness)
mm mils
w (Trace width)
mm mils
εr (Relative permittivity)

 (Characteristic impedance)
C0 (Capacitance)
pF/cm pF/inch
Tpd (Propagation delay time)
psec/cm psec/inch
