Need to calculate track resistance?

The TRC100 PCB Track resistance calculator lets you enter track shape and length, along with material type, the TRC100 will give you an answer in Ohms for the trace you describe.

TRC100 is useful if you are working on fine geometries, and need to take care about series loss. You may also find TRC100 useful in power supply applications.

(If you need to calculate PCB Impedance, please look at the Si8000m Controlled impedance design pages)
