Are there some formulas for how one can calculate the steady state temperature (or temp rise) of a wound air solenoid at a given high frequency and applied current through it?
This would be for frequencies around 10MHz for example.
The solenoid would have physical dimensions but just looking for a way to incorporate those dimensions into a calculation.
As an example problem:
freq is 10MHz
applied current is 4Arms
inductance is 400nH (about 25ohms reactance)
the Q of the solenoid is 300 (then the calculated resistance is 0.084 ohms, which is R =|25|/300)
the power dissipated is I^2 * R, which is 4*4 * 0.084 = *16 = 1.34W
How do I get a temperature from this point?
