Damaged Motor Shield, Need new cap

If this is in the wrong section, I apologize...

So I was messing around with my motor shield, trying to clean some glue off, when my tool slipped and knocked off a cap that was soldered right between the "3.3v" and "5v" labels (this one, circled in red: http://i44.tinypic.com/igdchw.png). I'm wondering what type of cap this is, and where I could get a replacement one to solder on? I haven't tried using the shield since I damaged it, for fear of damaging it further.

Thanks
