The FB component designator is often used for Ferrite Beads. I am a bit amused by the fact that the FB2 designator is used twice here.
Ferrite beads are used for high-frequency noise suppression.
Same family of components, I suppose... But they are used differently and have different characteristics. I think this page from Rohm Semiconductor provides a very good explanation as to what the contrast between the two kinds of components is: https://techweb.rohm.com/knowledge/emc/s-emc/04-s-emc/8138#:~:text=Ferrite%20beads%20are%20classified%20as,be%20utilized%20in%20noise%20elimination.
Thank you. So I can see them as low value inductors?

Thanks for the web.
