Inductance of a straight wire
This project was originally made in 2011 in Excel format. I converted it to html and Java script in 2021.
When wiring RF-circuits, connecting straight wires act like additional inductors. Following calculator can help to estimate the magnitude of those stray inductances, to be taken into account.
Formulas
Lac = 0.2*L*[ln(4*L/d)-1.00] nH , where Lac is the inductance in nH, L is the length of the wire and d the diameter of the wire, both in mm.
Calculator
Give length L of the wire in mm.
❶.Give diameter d of the wire in mm
❷.
