Impedance Calculator

Plug-In category: EMC, other Plug-In included in: PCBI Developer, PCBI Ultimate

Use the Impedance Calculator to quickly calculate the impedance or AC resistance of conductors in your PCB design.

The calculation is based on the IPC-2151 standard.

The increasing complexity of electrical components and circuits requires ever faster signal flows and thus thus higher transmission frequencies.


Impedance control is particularly important for high-frequency tracks. The plugin allows you to guarantee the same by calculating the impedance for each individual selected trace with just a few clicks. The impedances are mainly determined by the trace geometry, the layer structure and the material used (e.g. dielectric constant (εr)).
