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 = ?
" is symbol for inch, I already translated to mm. These are self-elaborated coils, no part number, unfortunately no specified inductance. You can estimate the typical inductance by referring to online calculator tools, e.g. https://www.qsl.net/in3otd/indcalc.html
