Parallel Wire Impedance

Calculate the impedance, inductance, capacitance, and propagation delay of a parallel wire transmission line.

Computes the characteristic impedance, distributed inductance, capacitance, and propagation delay of a two-wire parallel transmission line from wire separation, wire diameter, and relative dielectric constant.

Inputs

Wire Separation(mm)

Centre-to-centre separation between the two wires in millimetres

Wire Diameter(mm)

Diameter of each wire in millimetres - must be less than wire separation

Relative Dielectric Constant

Relative permittivity of the surrounding medium - air: 1, PTFE: 2.1, polyethylene: 2.3

Results

⚠Wire diameter must be greater than zero

Inductance-nH/cmDistributed inductance per centimetre in nanohenries

Capacitance-pF/cmDistributed capacitance per centimetre in picofarads

Parallel Wire Impedance-ΩCharacteristic impedance of the parallel wire line in ohms

Propagation Delay-ps/cmPropagation delay per centimetre in picoseconds
