    I did a boo-boo and managed to fry (ooo, what a stink) a brand new
    remote switch for our xmas lights. As you can see from the attachment,
    it is definitely a dead cap (the smell was from a resistor on the same
    board).

    My question is, what's the value of the cap? I am guessing .00022 uF
    at 250V. I have a pretty good junque box, but don't want to kill this
    little gadget for sure with the wrong value.

    It's a 300-MHx 2-ch receiver driving two relays that switch two load
    circuits (lights).

    At least there are two good relays to salvage!

    I'd be guessing it's actually 0.22uF (22pF x 10^5). How big is it?

    Cheers.

  3. The glare is on it, but assuming I read it correctly it says 225J and 250 on
    it. This would strongly imply 2.2uF 5% 250V rated polyester.

    This is of course better maths than my feeble attempt. Mental note - get cup
    of tea.....

    225J and MEF250. Thanks guys. I left the electronics game as a
    gainfully employed soul in 1979, but never stopped fiddling and
    building stuff. As a ham, that's required, isn't it? I guessed at the
    value based on the 22 and the 5, but started at the wrong place and,
    well, the rest is history.

    Mo' tea?

    Thanks again--

    About 0.75L and 0.5 x 0.625D (oval).
