Calculate the differential impedance of microstrip traces on a Printed Circuit Board (PCB) with our efficient online calculator.

Differential impedance refers to the characteristic impedance between two lines when they are driven differentially. Microstrip is a straightforward and practical method for creating transmission lines on a PCB. Utilize our online Microstrip PCB Differential Impedance Calculator to accurately calculate the differential impedance of microstrip traces on a Printed Circuit Board. Input the values of characteristic impedance, trace height, and spacing between traces to obtain precise results. Simplify your design process and optimize your PCB layouts with this convenient calculator, empowering you to achieve accurate and reliable differential impedance for your microstrip circuits.

    d = 2 \cdot z \cdot (1 - 0.48 \cdot e^{-0.96 \cdot (s / h)})

    where,

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