This calculator calculates the characteristic impedance, capacitance per unit length, effective propagation delay, inductance per unit length using relative permittivity, height of dielectric, width of trace, trace thickness values.
Formula:
z = 87 / √(e + 1.41) × LN((5.98 x h) / (0.8 x w + t))
c = (2.64 x 10-11) x (e + 1.41) / (LN((5.98 x h) / (0.8 x w + t)))
p = (3.34 x 10-9) x √(0.475 x e + 0.67)
l = c x z2
z = Characteristic Impedance
e = Relative Permittivity
h = Height of Dielectric
w = Width of Trace
t = Trace Thickness
c = Capacitance per unit length
p = Effective propagation delay
l = Inductance per unit length
