Wire Gauge, Current Limits and Maximum frequency for 100% skin depth (no skin effect)

[Tahmid]

Here you find information about load carrying capacities and maximum frequency to avoid skin effect of copper wire. There is an online calculator as well.

thanks! I also give some experience data, for power transformer, I select current density 3-5A/mm*mm to design diameter of wire, for mode choke, I select current density 8-10A/mm*mm to design, for SMD power inductor, select current density 20-30A/mm*mm.
