The inductor claims to be rated at 1mH @ 16A DC.
The core is iron powder od=26mm, id=14.5mm, h=20mm with a relative permeability of 6000, and the winding is 10 turns.
From this I calculate a cross sectional area of 115mm^2 and a magnetic path length of 63mm.
I've never seen iron powder with μ greater than about 180, so I wonder if it really is ferrite.
10 turns at 16A is a magnetomotive force of 160A. Permeance (Al) is 10μH/t^2, reluctance is 100000
That gives a flux of 1.6mWb and a flux density of 13.9T.
