** Its an X2 class, 275 volt AC mains cap.
Suitable for connection across active and neutral .
Removed from a broken (caught fire!) fanless power supply (fanless PC power
supplies are NOT a good idea - Yesico was the manufacturer if you want to
avoid them).
It was right next to the AC input, so I assume it's a filter capcitor (to
remove high frequency noise?)
It says on it 0.33uF, and my multimeter agrees.
But, when I tried to use it in a circuit to limit AC current, it did not
limit. I expected it to limit the current twice as much as a 0.67uF
capacitor which I had in the cirucit previously. It limited it a lot less,
as it blew stuff! Replaced blown components in circuit, then put this thing
in series with the original 0.67uF cap. It did not affect the current at
all.
Is there something other than a capacitor in here?
** Nope.
Ohmeter shows infinite resistance both ways.
** Try connecting it across A and N - see if it explodes.
BTW
The lack of LHS indent markers with your post is bad usenet practice.
Fix it.
