Hi Giulia,
Its a 330uh (micro Henry) shielded SMD(surface mount device) power inductor,
Gettable on ebay… here is an example.. many more listings…
https://www.ebay.com/itm/10pcs-CD127-33uH-330-Shielded-Inductor-SMD-Power-Inductors-12x12x7mm/282483448019?hash=item41c55358d3:g:KV0AAOSwhvFZJQPt
And at a really good distributor,
https://www.mouser.com/Passive-Components/Inductors-Chokes-Coils/Fixed-Inductors/_/N-wpcz?P=1z0wrdt
Were they both they same component? I didn’t see a second one?
Hope this helps..
