    I am looking for an air-core inductor that can output 30A. Is there any commercial product available? otherwise i need to build it by myself.

    What inductance value do you need?

    12nH.
    If the duty cycle of the current that flow through the inductor is 7.5e-7, the peak current is 10A. what is the rating of the inductor?

    To get a 12nH inductor for up to 30A, you need a straight piece of AWG-10 (2.59mm) copper wire about 842 mils long.

    Sure you didn't mean uH or mH?
