And the particular type of ferrite matters since different ferrites have different curves of loss v. frequency.
And some inductors are gapped and some are ungapped. Gapped inductors have much more tightly controlled
parameters as the gap mostly determines the properties. I think most/all of those links refer to
gapped inductors - ie the magnetic circuit is not a complete ring of magnetic material, so somewhere
the flux has to flow through a non-magnetic material (air, plastic, whatever).
In fact, all the inductors cited in the OP are completely gapped as they are essentially, an open bobbin with the wire wound in it.
I am not so sure about the "chip" sort - presumably the winding is printed onto the ferrite and would have a vastly higher resistance making them completely unsuitable for power conversion, being essentially for decoupling of low current loads.
