I need a capacitor for the attached simple circuit - it's for motor direction reversal. The diagram says I need a .75-MFD, 330 VAC capacitor, but I can't seem to find one anywhere online. I know the problem is me, I'm sure they're available.
I'm embarrassed to admit it, but I have forgotten what the "MFD" means - is that "microfarad"? Is that the same as "uf" (the "u" being the greek letter with the tail)? And what kind of capacitor - oil-filled, electrolytic, ceramic, or some other?
Can anyone please indulge an idiot and post a link to a capacitor that will be appropriate for this circuit...???
I have no problem finding the designated resistor, in case you were wondering.
Thanks,
Doug H.

 

Plenty on Ebay.

0.75 microfarad(uF) is 750 nanofarads.(nF)

 

Look at the WIMA pulse duty Polypropylene capacitor .68uf 630VDC/400VAC Mouser PN. 505-M10.68/630/10.

The value should be close enough for snubber duty.

 

$1.87 at www.mouser.com, but they might be high on shipping charges.
Point is, they are called "film" capacitors or, "polysomething" capacitors, and any voltage higher than what you need will work.
The DC conversion for 330 VAC is 467 volts DC. If the capacitor you find doesn't say, "VAC" you will be looking for at least 500 V DC.

MFD seems to be an older convention for large size caps. For your single phase motor it may possibly be a Metalized Polypropylene Film type. I just ordered a 5uF 450VAC (from Amazon of all places) to replace the burnt out one in my bread machine which is part of the motor start up cct.

 

Thanks so much guys, I appreciate your help a lot.
