skin depth chart

[exxos]

Hi all,

Does anyone know of a simple skindepth chart for copper wire running at high
frequencys around the 100khz mark ? from what I can work out skin depth for
copper at 100khz is about 0.1mm though a accurate charts would be helpfull.

thanks,
Chris

I love to cook with wine. Sometimes I even put it in the food.

Hi,

I can't make any sence of that image, I'm also not good with the math

Cheers,
chris

You'll have to deal with the math, since skin depth is a function of
conductivity, permeability and frequency. And the math is butt
SIMPLE!
