Usually only electrolytic caps are polarized and I have in all my years
never seen an electrolytic good for more that 650VDC. Chances are your caps
are film and are not polarized.

Hi, i dont think those type of caps care which is positive or negative,
unless marked. the rating still applies to the maximum dc voltage. cul brian
