What are these caps?

[tmcw]

Have this old Asus/HP motherboard (A7V-VM), and it has mainly Rubycons on it, but there is a small riser board near the SD-RAM slots populated with yellow and black capacitors. The following link has a similar motherboard, you can see the caps in the photo, and zoom:

Above the V/F value and temperature rating, there is a capital "F" with a bar above and below the "F", like this...

Can someone tell me what brand these caps are? I haven't seen ones like this before.

Those are Fujitsu hybrid polymers. Good caps. No longer made.

Thanks for the info, I've seen them discussed a couple of times here.

I was just stripping the board, and wondering if they were worth keeping. They have low ESR, but the capacitance value is quite a bit higher than what's on the label, eg, 680uF reading about 800uF, and 820uF reading just over 1000uF.

Anything to be concerned about?

They're within 20% tolerance, so should be okay.

Where did you major in math - they are both above 20% out
