As I was re-reading Boswick's RF Design book it occurred to me that I
may have overlooked something very fundamental.

I often transform components from series to parallel form, and visa
versa ,depending on what I am wanting to achieve.

What I have over looked is. What form do manufacturer's state Q and
inductance ?

I took a look at a coil manufacturer's specs and they don't explicitly
say whether the test circuit was series or parallel. I would assume that
the standard would be series form ?

Would someone please advise me which it is ?

Though the Q would be same in either form, the inductance and loading
could be slightly different.(ie. If I have assumed series form then when
I transform into parallel form and calculate a specific Rp and L it
would be incorrect if the inductance and Q in the manufacturer's data
were specified in parallel form.)

Hopefully someone can make sense of what I am getting at here.

Thanks in advance
