So a lot of graphics cards was brought home.
And theese fellas were found in the box:

They belong on a GF2 Ultra so i kinda want to make it work.
But since identifying SMD stuff seems to be a black art I need your help!
I'm assuming the "330" is the capacitance, they measure about 300 uF
But the rest?

Only similar size caps I have are marked:
251
330
6z
But I'm guessing I wont be lucky this time.

330MF 6.3v. Here is a pic of some Sanyo SVPC 6.3V 330UF SMD that have nearly identical markings..

Looks pretty similar!
Now I wonder if the letter "E" has any significance, I'd bet it has or it wouldn't be there.

Probably a ripple current rating, since it is on a video card it would be like one in a switching PSU or board VRM and be high current/low ESR. Just about any good capacitor should work though. If you know which video card it came from it would help.

If going by this pic found on the eevblog forums:

I should be fine using the caps I already have.
Or at the very least the spec wont be so far away as to damage anything.
