Brilliant, uniserver! A non polarised replacement!
I'm no expert on whether the esr is OK on those, but it does say it's low. I am continually amazed at how technology is advancing. We would never have thought of getting a 47uF capacitor in ceramic just a few years ago.
However, it's no better solution than putting a polarised electrolytic or tantalum in with the correct polarity.
Maybe another solution is to leave C22 off the pcb.
Maybe someone like the techknight has an oscilloscope and can put a probe on the -5v supply when two of his Macs are transfering a file on Appletalk and see if the supply is degraded at all with no C22. I've seen his YouTube videos. He knows what he's talking about.
