Power Handling capacity of Inductor

[Shadow_warrior]

I want to select a core for inductor. Specs are as follows:
I max=30A
I min =10A
L=10uH
voltage across inductor = 60V
on time = 4us
total time =10us
What should be the power handling capacity of the inductor core?
Also, Does it even matter while selecting the core for inductor.
Note: I am selecting core using Area Product method)

Yes, core material matters for power (saturation current). For frequency too. I think you need a ferrite core with that pulse width. Ferrite doesn't have the best power handling. Sorry I can't help more. Magnetics is not my thing.

What are you doing with it?

There are a little small but: SER2915H Can you use two 22uH in parallel or two 6.8uH in series?

 

[ronsimpson]

This is too small also but another place to look: WE

I have never used one of these: TT

I want to wind on my own.

Look at the core size and wire of the coils I found and know "like that but bigger".

Voltage across the inductor says nothing about the total voltage that is delivered to the load, so from the parameters you gave you cannot say how much power can pass through the inductor. A circuit diagram where you want to use it would be nice and remove some questions.
Also you need to know the max. RMS current in the inductor, so that you can calculate the crossection of the wire.

RMS current in the inductor, so that you can calculate the crossection of the wire.

Yes, rms for the wire but that is the only time I use rms. In this case I would use Litz wire or copper strap. 30A
I would keep core saturation away from 30A. Peak current in the worse case conditions. I do not like to saturate under a short circuit condition.
Look for core loss with a P-P current of +10 to +30A.
Just to double check my answers I check core loss and saturation using VT and also LI.

What should be the power handling capacity of the inductor core?

With out knowing "boost" or "buck" or "isolated", or ….. I can not guess what the power is?

Have a look at ferroxcube's (now philips?) Etd series of transformers.
You can use them as a 2 lead inductor.
Maybe something like an Etd44.
