Via Inductance

Via inductance calculator based on "Modeling Via Grounds in Microstrip" IEEE Microwave and Guided Wave Letters, Vol. 1, No. 6, June 1991, by Goldfarb and Pucel. This calculator is valid only for vias connecting microstrip lines to the ground plane with no return paths on the top layer (ie. no coplanar modes).


Distance units: 

Substrate Height, h  
Diameter, d  
Inductance, Lvia pH
