Sourcing capacitors MacBook Air

I have a MacBook Air 13” 2011, EMC 2469 that has issues with high fan noise and laggy performance on boot. I’ve taken the logic board out and found corrosion on one of the capacitors (C9331 according to the board schematic I have). When trying to scrape it off, the capacitor literally just came away, so I think I found the culprit!

Being a newbie to board repair, but having nothing to lose because the MacBook cost me nothing - where can I get a replacement capacitor? I have searched Digi-Key but don’t really know what I’m looking for.

Many thanks in advance for your help
