Use this electrical engineering calculator to calculate the trace width, Capacitance per unit length, Inductance per unit length and DC resistance per unit length and propogation speed given the Target impedance (Zo), trace thickness, dielectric thickness and relative dielectric constant.

Code to add this calci to your website  #### Formula: w = (((7.48 * h) / e(Zo*(√(er + 1.41)) ) / 87)) - (1.25 * t)) Tpd = 3.333 * (√((0.475 * er) + 0.67)) * dimension; C = Tpd / Zo; L = Tpd * Zo / 1000; Dc = (17.2 / (w * t * dimension2)) / 1000;

Where, w = Trace width er = Relative Dielectric Constant h = Trace Width Zo = Single Ended Microstrip Impedance t = Trace Thickness Tpd = Propagation Delay C = Capacitance L = Inductance Dc = Resistance if dimension unit is mm then dimension=1 if dimension unit is mils then dimension is 0.0254
