    Default Need Help Finding 0.75 mfd capacitor

    I am in need of finding 0.75 mfd - 330 VAC capacitors. Can anyone help????

    I would try:

    Radio Shack
    Allied Electronics
    Mouser
    Jameco

    Allied probably being your best bet.

    I should think a higher voltage rating like 370 volts would be ok so long as it was still .75 mfd.

    So might have better luck searching for this by not including "330".

    Also capacitors are abbreviated uF

    So maybe search for

    .75uF capacitor AC

    or...

    .75uF capacitor 370 AC

    or 370 vac capacitors

    (Might call and ask some of the places you find with the last search.)

    Any electronic store such as the ones mentioned, or Frys, should have something. What is your application? If it is something like HVAC then a 370 VAC might be a better number. 1.414 X 240 = 339 volts!

    But if the application calls for 370, it is available I am sure. In most applications, there is no downside to using a capactor with a higher max. voltage rating.

    Depending on your application, try Grainger.
    Two 165v 1.5 uF in series will give you 0.75 uF @ 330vac [but you need some voltage sharing resistors] , or two 0.375 uF 330v in parallel will give you 0.75 uF @ 330v.

    And what's your tolerance on the 0.75?

    The voltage rating on a capacitor is essentially its insulation rating...the point where it might short out by flashover or piercing the insulation layer. So, normally, using one with a higher voltage rating isn't an issue.

    http://ca.mouser.com/Search/Refine.a...VAC+capacitors

    Do you have a parts number? or a company?
    Check this out, maybe, http://ph.mouser.com/Passive-Compone...tors/_/N-5g7r/

    http://itemlistings.****.com/sdcsrp?...52&xm&var=ngvi Do a search on e b a y I found one.

    Type in,
    MALLORY 72-86MFD 330 VAC PSU7230B 235-9528-04 CAPACITOR I would think, this would work, 9.50.
    If I am wrong, please don't chop my head, just not enough information, but i hope this helps.
