Which specific resistor for component 'L8300' on MacBook?

I fried a resistor attempting to clear out some water damage on my logic board. It's the one at the bottom of this photo: (edit: see better images added below)

According the the board diagram and spec, I think it's L8300, which is labelled on the spec as 'FERR-220-OHM' and '0805'. However, when I search on digikey our mouser there are hundreds of matches. Does anyone know which one is the right component, and any tips for replacement?

Thanks!

Edit - better images as requested...

@petemill "the one at the bottom of this photo" is really not descriptive. Post an image where you mark the component so that we can check which one it is. You say that you " think it's L8330" that needs to always verified. L8330 does not show up in my schematics. Let us know what the logic board 820-XXXX number is. Reference designator "L" means that the component is an inductor. 0805 is the package size of 0.08" x 0.05" of the component.

@oldturkey03 thank you for your comment and your advice on how to ask the question better. My mistake, the component is L8300 (not L8330)! I've added 3 photos: one photo with the corresponding area highlighted (this is not my photo, but ifixit's photo), another with the corresponding board diagram location, and another with the schematic location. I hope this helps you help me better!

@oldturkey03 do you think this inductor is a good replacement? http://www.mouser.com/ds/2/54/RF2012A-77...

@petemill excellent edits and great idea to add the images. Yes, that inductor looks like it would work for your board.
