Inductor and transformer design is an iterative process. One place to start the iteration is to make a guess based on core losses. On the web, I found 2 different rule of thumb values: 100 and 300 mW/cm3. Neither of the application notes said enough about temperature raise or air flow. Folks, what values are you typically using? Could you shed some intuition* onto this?
* I'm looking for shortcuts. I do have an idea about how to do this rigorously: calculate losses, apply thermal resistance, compare to max temperature raise.
