Performa 6400 Capacitors / Recapping

[sulley86]

The time has finally come that the caps on my Performa 6400 begin to leak. Now, I was just in the process of making a capacitor list when I stumbled upon weird markings on some caps. For example, three caps on the logicboard read:

100
JFK.
FD0

I am not an expert, so can someone explain if there is any info about the voltage in these markings?

EDIT: I just found this page  where two 100 µF 16V and two 100 µF 10V caps are listed. I'd still be interested what the markings mean.
EDIT 2: Ok now I am even more confused. Another page shows these caps as 100 µF 6.3V.

I have a 5400 board, and the macdat image matches the one I have. However, mine does not have the set of empty pads between the marked capacitor and the big chip on the bottom, that area is just empty on my board, and my reference numbering is slightly different. So there may be multiple revisions of this board.

The Retro Tech Collection one you linked has some very strange values. I can't say I have encountered 22µF 16V on a mac logic board, nor is 100µF 10V a value I can remember seeing on any of the dozens of logic boards I have recapped - and the capacitor numbers don't match what I can see on my 5400, 5500, or 6500 boards at all! So I would not trust the Retro Tech Collection page.

Maybe if you can recover the marked cap in a nondestructive way and measure the capacitance to give you an idea? Or someone might know what kind of power rail it is sitting on?

100µF, and the JFK, as I understand it is J=6.3v rated voltage, FK=capacitor series.
