Stripline represents a transverse electromagnetic (TEM) transmission line medium frequently utilized on printed circuit boards (PCBs). Obtain precise outcomes for PCB impedance assessments using this straightforward tool.

Effortlessly determine the impedance of a stripline with the help of our user-friendly online PCB impedance calculator. Stripline, a transmission line medium commonly realized through printed circuit boards (PCBs), can be effectively employed. The stripline’s impedance, measured in Ohms, can be readily calculated through this tool. Furthermore, you can also acquire data such as capacitance, propagation delay, and inductance linked to the stripline using the Stripline Impedance Calculator.

Stripline Impedance formula

    \[z = \frac{60}{\sqrt{e}} \ln\left(\frac{1.92 \times (2h + t)}{0.8w + t}\right)\]

    \[c = \frac{5.55 \times 10^{-11} \times e}{\ln\left(\frac{3.81h}{0.8w + t}\right)}\]

    \[p = 3.34 \times 10^{-9} \sqrt{e}\]

    \[l = c \times z \times z\]


  • e = Relative permittivity of the dielectric
