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

Subject: Re: Split Ceramic Disk Capacitor
to
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 ceramic disc capacitors.
