I have been studying the etherten schematic and was stumped about the value for inductor part L3?

Great product design!

Hi Ali,

I've split your post into a new thread as it wasn't related to the thread you posted in.

L3 is mislabelled on the schematic, I just changed the label to "0805 FERRITE". Almost any ferrite bead with a low DC resistance (ideally <15mOhm) should be fine. We specify one with a DC current rating 2-3A, to keep some headroom.
