Subject: RE: Split Ceramic Disk Capacitor
I don't know, but thanks for pointing out that it might not be a
capacitor.
I have two more VLCs so I will open them up and see
what the markings are,
the markings on this one are almost illegible.
Thanks
Rob
I have just opened up one of my other VLC machines. The part in question is
marked
.0033M
Z5U
I guess this means a 3.3nF capacitor? Or will it mean 3.3uF?
Thanks
Rob

Since I am forced to stay at home more than I would like I though I
would check some more PSUs. One I wanted to check was the H7109-C
from one of my VAXstation 4000 VLC machines. I found a leaked
capacitor and some other high ESR ones, so I will replace those.
However, I also noticed a ceramic disk capacitor that appears to be
split all around the edge. Is that a known failure mode?
Is it definately a capacitor?
I've had some damaged surge arrestors / MOVs / VDRs that look very
similar >
