A tool designed to calculate the characteristic impedance of a twisted-pair cable
Please enter your values below.
A twisted-pair cable is simply two wires that are twisted together so as to reduce radiated EMI (electromagneticinterference) and mitigate the effects of received EMI. Twisted pairs are used with balanced signals. It is important todetermine the characteristic impedance of a twisted-pair cable because this impedance should match the impedance of the transmitting and receiving circuitry.
This calculator computes the characteristic impedance of a twisted-pair cable based on its dimensions. This tool will also provide the signal propagation delay, capacitance, and inductance per unit length.
