Small, toroidal inductors can be wrapped very crudely and still perform surprisingly well. Just make sure to use magnet wire when you wind. I would recommend a bobbin to hold the toroid when you mount it on the PCB and use a foam adhesive to suppress any physical vibrations that can develop from magnetostriction when pushing at core with high magnetic fluxes.If I could buy a 100uh toroid inductor 30a that will be better than winding my own.
Reducing the noise due to magnetostriction is no easy task. It requires a deep understanding of the forces acting on and in the core laminations that only electromagnetic field simulations can provide.
