In most circuits the UNLOADED Q of an inductor is made as high as possible as Q =ωL/R the R represents a loss. The LOADED Q of the circuit, is the ratio of the reactance to the reistance and so is determined mainly by the load. i.e. You can get a L with a Q of 100, put a 100 ohm resistor in series with it, the CIRCUIT will have a Q of 5 (depending on ωL). If you have a tuned circuit in the collector (or drain) with a Q of 100, its loss is infinite, no load no power transfer, now if you couple that tuned circuit to something else so its loaded Q is 50, its loss is 50%, but you get a signal with good selectivity. If its a power amplifier, the coupling to the load will be tighter, so the loaded Q is 10, its loss will now be 10%, but with only a little selectivity, just to reject harmonics? But in all cases the individual components will be made to have a high a Q as possible.
