Looking at the EEM, the description and notation seems to be United Chemi- con who does have a web site at www.chemi-con.com bs

Judging from the location, it doesn't look like a DC-DC output cap, but rather a bulk supply cap for the graphics processor. The DC-DC converters are nestled in that jungle of tin cans at the up-end of the board. That said, it could very well be a tantalum... 16VDC is a pretty high voltage for a solid polymer cap in that large a capacitance...
Anyway, check out AVX TPS series caps for a replacement... they're probably available at digikey in onesies... perhaps a TPSD476M016 E

Here are pictures of the capacitor. http://reddragoncanoeclub.org/paul/9600/
The card is just to show the location and relative size of the cap. The only difference is that my cap is black and my board is green. heh.
I was assuming the cap is tantalum.

What package is the bad capacitor in and what chemistry was it? Chances are it was a low-ESR polystyrene or aluminum-polymer cap, in which case you do not want to replace it with just any off-the-shelf tantalum or electrolytic capacitor. The DC-DC converters on video cards are ultra-clean and depend upon a very low amount of resistance in the output caps to minimize ripple.
Was this thing a round tin can? E

Nevermind. heh. I will try the radial capacitor. (I found #electronics on Freenode.net)

I have a Radeon 9600 Pro video card with a bad surface mount capacitor (C2). I'm not sure of the value of it. It's labeled "47" and "16V" which I read as 47uF, 16V. Does that sound correct? It is a black SMD capacitor with a white end to indicate polarity. The size is roughly 7mm x 3.5mm x 2mm. I need to identify it enough to replace it. Would it be too wacky to use a huge radial capacitor to replace it? ___________________________________________________________________________
