Because my electronics dealer didn't have either of those, I tried to compare the data and took the one I linked first.
Did I make a mistake there? I don't really undestand the data from ferrite beads.
The datasheet doesn't help much either as I can only find "bead" in this picture:
Here is the schematic from my board. Ignore Q4 as it was removed and bridged. L1 is the bead.
Overall, my ESP gets the clock signal but can't initialise the PHY (LAN8720) chip and my RJ45 doesn't get enough power, either. (The diodes don't go on.)
