Switched on my ultrasound cleaner which worked fine for 10 minutes then it started spewing out smoke ! So a capacitor has blown apart, anyone know where I can identify and obtain a replacement. It looks like the value is .22 uf and rated 400v/220v.

Do you want me to upset you...
I had one of those ultrasound cleaners that my son was given to him from work.. He gave it me and I dont know why as never used or needed one.. Sold it Monday at the boot sale... £5..

Just looked them up and seen the prices :Eeek: someone had a real bargain.

Thanks for the suggestions, hopefully ordered the correct one from Maplin, £1.59 and a 3 day delivery to my local shop. Anyone know if these things are polarity sensitive and if so, how do I tell the orientation of the original unit that's still on the board ?
@tonka, I got mine from work too, it's a nice small industrial unit, much better than those "jewellry cleaners" you see advertised. I'm going to use it to try and clean a Mikuni cabuerettor off my log splitter, one of the jets was blocked which I managed to blow out, but I suspect the drilled pasageways for the pilot air screw may be blocked as I can't get it to tickover very well, it's always "hunting" but settles down with a tiny bit of choke.

It looks like it was probably an X2 capacitor which means it goes across the line in an AC circuit. With it being for an AC circuit I doubt it will have a polarity but check the packaging.

Don't take my word for it though, my electronics knowledge is dated.

Why does anyone want to clean ultrasound?

How does it get dirty?

JJ :cool:

Yup, it's on the can type capacitors, but it's the rectangular yellow one in the middle that's needing replaced. Incidentally, the bath kept working even as the smoke was billowing out, it looked like a hi-tech witch's cauldron :LOL:

Aha - then I'm stuffed, unless it's distinguishable on the underside (n):notworthy:

When the replacement part arrives ask google to find a datasheet for that component part number. That should tell you all you need to know regarding polarity..
