I think that rippe current is rarely considered and rarely given by makers, which is why I tend to stick to Rubycon electrolytics from Farnel, because they're 105C and have high ripple ratings despite their compact physical size. Furthermore, comprehensive data is available so you aren't buying a 'pig in a poke' where he only factors you know about are the capacitance and working voyage. You can check whether they meet the desired ripple rating spec. EG:

I use the compact high voltage ones for stuffing smoothing/reservoir caps, as I can check that despite their diminutive size, the ripple rating is well up to the task with a good margin of safety.
Hope that's of interest.
