L3405 and the capacitor next to it is C3422 (capacitor burn might clean up with isopropyl though).

L3405 = 120 ohm 1.5A 0402 ferrite bead

C3422 = 0.1uf 20% 10V 0402 capacitor

Thabk You so much for your help.

So the burned one is L3405?

And c3422 is under the burned one or the right one?

I think i just change the burned one l3405


Destroyed one is L3405, C3422 is to the right of this. Yes, just replace L3405 and clean the burnt capacitor, usually it is just residue, the capacitor should be ok.


Would that one be ok?

I cant find how much A this has.


Yes that looks ok. Might be worth emailing them to check the amperage though. Just email them, say you're looking for a 120 ohm 1.5A 0402 ferrite bead and they will point you in the right direction.


Insaw the Soldering point on PIN17 but i cant find the other soldering Point
