This calculator calculates the capacitance per unit length using relative permittivity, height of dielectric, width of trace, trace thickness values.

Pcb Capacitance Per Unit Length Calculation

mm
F/m

Formula:

c = (2.64 x 10-11) x (e + 1.41) / (LN((5.98 x h) / (0.8 x w + t)))

Where,


e = Relative Permittivity
h = Height of Dielectric
w = Width of Trace
t = Trace Thickness
c = Capacitance per unit length
