Ok you people that use this everyday - I have a ceramic disk capacitor from
a power supply that went south - brown and cracked. I can read the etched
value on it though but it's been a long time since I've seen this type of
marking. It has as follows:
(first line unreadable, looks like MDE)
2200M
X7B or X78
1KV
I see it as 1 kilovolt, that's obvious but I've been using the new system
that is in picofarads and not sure if that is supposed to mean 2200 uF or if
it is some old way of marking 2200 pF. Also what would be the current
marking number system equivelant (ie 222, 224, etc) for replacement. Most of
my "junk box" parts are new system markings and I am not in the mood for a
fire or replacement of other items if I get it wrong.
When put on a cap tester I get 100pf which I feel is wrong and may be due to
a shorted state or something. Capacitors have never been my strong point in
identification.
