Where can I buy this fuse?

I’m pretty decent at soldering, and I’ve actually successfully repaired one of these before by taking one off another computer, although I can’t read it schematic so I don’t know what the part number is.

@rickcostel that is not a fuse but an inductor. To be exact that is reference designator L8300 which is a 220 Ohm Ferrite bead in a 0805 package.

Something like this will work

Thanks, that’s a really cool website, i’m waiting for them to approve me.

Do you know if there are any more of these on the Logic Board, or any other Logic Board?


@rickcostel that particular ferrite bead is used by Apple across many models. It might be easier if you let us know which boards you have so we can check on those. Do an online search with the term L8300 and you find many places that sell them. That way you don’t need to wait for any approval.


My most plentiful is MacBook Air and Unibody 13, 15 & 17, but I also have a few retina, Touchbar, Imac, Mac Mini, etc.


@rickcostel I know these have it for sure

MacBook Pro 15" Retina Display Late 2013

MacBook Pro 15" Retina Display Mid 2012

MacBook Pro 15" Retina Display Mid 2014

Macbook Pro Retina A1502 820-4924, 820-3536, 820-3476

As for the rest of your list, it would be easier just to post the Apple board numbers. That way we can make sure by the schematic.
