Need help with coil inductor marking and reading !?
what does it mean?

I got this from datasheet MRF426, so I can't convert its parameters into real inductor values = ? uH
L3 — 7 Turns #20 0.38″ ID
7 turns = number of turns
#20 = ?
0.38" = ? copper wired diameter ?
ID = ?

0.38" = 9.6 mm copper wire? serious?

It's AWG 20 (0.8 mm) copper wire, ID is coil inner diameter.
Thanks, so what does it means of 0.38" = ?

Anyway,
L1 — 3 Turns #16 0.25″ ID = ?uH
L2 — 6 Turns #16 0.5″ ID = ?uH
L3 — 7 Turns #20 0.38″ ID = ? uH or part number please
