>You are nearly right, Q is  the reactance divided by the equivalent
>resistance, that's the sum of ohmic losses plus the RF losses.
>Generally speaking anyway, what counts is often the circuit Q rather than
>the single component Q.
>For example, after all this is the AMP reflector, one can build a coil with
>Q=300 but the PI network where that coil will work could have been designed
>for a loaded value Q=10 (or even 2) , thus accepting lower quality inductors
>without any practical problem.
>Incidentally, sometimes the current and dissipation capabilities, rather
>than the Q, are much stringent parameters with inductors.
