Removed from a broken (caught fire!) fanless power supply (fanless PC po= wer supplies are NOT a good idea - Yesico was the manufacturer if you wa= nt to avoid them).
It was right next to the AC input, so I assume it's a filter capcitor (t= o 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 ca= pacitor 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 cu= rrent at all.
Is there something other than a capacitor in here? Ohmeter shows infini= te resistance both ways.
