    Do inductors vary with current as well? I would guess only a little
    bit.

    Yes.

    With saturation, yes, but what about the usable range?

    This datasheet shows a couple of typical inductance vs frequency charts:

    Over the non-saturated, nearly linear regions, inductance is slightly
    inversely proportional to frequency.

    Danke,
