In Reply to: Re: caps...rated at 660VAC, will they withstand 950VDC?! posted by kjt on October 31, 2001 at 21:11:24:
Why the extra 2 factor ?Isn't Vmax = sqrt(2)*Vrms ?
Then we would have Vmax = 1.4*Vrms so for these caps Vmax = 1.4*660 = 924V hence, no, they can't be used for 950V.I've got the 'same' problem, I've got loads of caps rated at 300V dc. I thought they were rated for AC when I bought them and now I'm not sure what to do with them..
Just like to be cautious with these things - I wouldn't like them to explode when there's people around.
There's two solutions: either sell them or use them at a much lower voltage.
