Hi all,

I have a question about inductor saturation current.
I designed 1.1mH inductor and its max current is 47.94 mA according to the core values.

I should calculate the resistance(for ac resistance I have to know frequency) of the wire and pulse width(it must keep inductor at unsaturated region).

How may I calculate both of them? The schematic of the circuit is shown below.
