What is this cap called?

What is this capacitor called, what size is it? And where can I get one? I just received a MTX amp to fix and it looks like the only issue is this cap, but I have never had to run across these before until now.
I am going to try to attach the picture.

Hi,

That's a surface mount electrolytic I believe. Almost everyone has those, Digikey, Newark, Mouser, etc...

100uF @ 25V if I read that right.

Cheers!

Great, thank you!

Now I found another bad one. 10 KFK 5K2 Would that be a 10 uF cap?

Hi,

Yup!

How are they bad? I know one's used in PC's are horrible little pieces of junk, but never heard of so many bad ones in an audio unit

Cheers!

They broke off the circuit board, I opened the case and 1 fell out, then after replacing that one I searched around for anymore loose ones and another one just fell off the board when I poked it, so I replaced them both with regular style caps as thats all I have on hand, now it's time to diagnose the big problem. Thanks for your help!

No problem!

Junk solder joints are the bane of many an otherwise decent design

Cheers!
