Are you going to use the naked inductor to give a notch at its SRF (the frequency at which it parallel-resonates without additional capacitance)?
The manufacturer's data are measured using standard frequencies (based on traditional Q-meters, q.v.) which are always below self-resonance, since they must be measured where the reactance is inductive.
Normally, you would use an inductor at a frequency below its SRF and add a capacitor (probably adjustable) in parallel to get a useful notch.
I've used some before without looking to deep into the Q factor for the purposes of a RF compensated Langmuir Probe and they seemed to have worked for the application. Its time to buy some more and after reading further into why these inductors are used, one of the papers cited a high Q value.
Just out of curiosity I hooked my sig-gen up to one of my previously purchased inductors with a set SRF and then into my scope and noticed attenuation close the SRF frequency.
Then I did the same with a network analyzer and it appears the attenuation was offset to the SRF by a few MHz.
I can try building a notch with an adjustable cap....so long as the adjustable cap is very tiny. I'll have to look into those. Thanks!
