My dad plugged my old GPS up with a higher amperage fuse than it could handle

What is this thing? Is it readily available (links would be appreciated)? Is it worth trying to hand-solder a new one on?

It has no text on it and most closely resembles the "crystal/oscillator" on this page:

though I'm sure I'm dead wrong

Using a higher amperage fuse likely didn't cause this, unless something shorted internally and the fuse didn't blow soon enough.

That said, I believe that is a smaller, more modern day Flux Capacitor.

It's hard to tell from that pic, it's kinda low res.

But it looks like either a surface mount resistor or surface mount fuse.

Just basing it on the orientation and resemblance of the other two components beside it - I'll put $1 on a surface mount capacitor, Bob.

^ or that

that seems more likely than what I said.

Can you tell me the part number of the 8 pin component to the left of this burnt out one? I'm guessing the little three pin surface mount to the left of your USB connector is a voltage reg, likely from the 5v usb down to 3.3. But I'd suspect this to be an LDO not a switching reg so I'm not entirely sure why that would blow up that cap. Quinn would know better about this.

thanks for all the input so far. If it IS a surface-mount capacitor, are they standardized by color? For example, are all turd brown ones of that size the same thing?

^ nope, they are going to have different values.

This is that IC to the left, it's a 2.5V part,

http://www.chipcatalog.com/Pericom/PI3C3306UEX.htm

so I'm pretty certain that is a Vreg next to your USB connector.

You could likely get away with any 10V cap (wouldn't even need to be surface mount) in place of what blew up if that is in fact a cap. Measure how big that part is and then go search for 10v caps that are similar in dimension and they should be pretty much the same capacity. X7R and X5R are popular/standard caps that will be a bit better than Z5Us for a vreg application (more important if that is a switching regulator).
