Actually, for MMC's, the things are so robust that some even take the DC
rating to be the AC rating.  I've done this with no problem at all.

Hi Raj...

are the caps marked WVDC ?  if they are then you will be looking for 
another set if you apply AC to them.
save those for a DC application and start looking for some AC rated caps 
...  DC caps really make a mess when they blow up from AC usage.
