Calculate the differential impedance of a stripline PCB with ease using this online calculator.

Calculate the differential impedance of a stripline PCB using this online calculator. Stripline is a reliable method for creating a transmission line on a PCB. Determine the impedance between two lines driven differentially using the characteristic values of impedance, space between traces, and trace height.

    d = 2 \times z \times (1 - 0.347 \times e^{(-2.9 \times (s / h))})

    Where:

    • d = Differential Impedance
    • z = Characteristic Impedance
    • s = Space between traces
    • h = Height of trace
