10 Amps Trace width

[Amr Wael]

Hello ,
I have been trying many calculators to get the correct width of trace that carries 10 Amperes DC (1 Oz 2-layers board) but the numbers differ from one calculator to another. Which range should I safely choose? Thank you very much in advance!

Thank you very much for your reply , I am using it too but I am wondering if it's reliable even for such high currents?

Hi,

10A isn't high current.
And the correct answer depends on many parameters.
Air flow, time, expected temperature, ambient temperature...
