Inductor characterization

[dtvmcdonald]

While thinking of the "white crud" coil problems of CT-100s, I
thought of "how do you adequately characterize an inductor?"
so one that matches that characterization "just works".

It would seem that you need four numbers:

1) Inductance at low frequency

2) DC resistance

3) parallel resonant frequency

4) Q at parallel resonant frequency

I was also thinking that for air core coils #4 might
be superfluous. Clearly for magnetic core ones it, or something like it,
such as Q if resonated at the expected operating frequency,
is necessary. It would also be necessary for shielded coils.

Does anybody KNOW the answer to whether this is good enough?
