can mundorf supreme caps be used for AC filtering

I have used Audience's Auricaps for across the line AC filtering for more than 6 years without incident. The Auricaps failure mode is open, posing no short-circuit/fire risk. I don't know about Mundorfs. I would at least investigate the failure mode of the Mundorf caps before using them in an across the AC line application.

Chrissain, you know that "AC rated" has nothing to do with the capacitor manufacturer's AC voltage rating right ? I just want to be sure we are on the same page. When we talk about "AC rating" for noise suppression use across AC hot and neutral, we are referring to the cap being X2 rated, i.e., the dielectric must be self healing or fail open so as not to pose a fire or electrocution hazard. Can you point to a source of information where it says Mundorf caps are X2 rated ? Regarding the Auricaps, I use 0.47uf ansd 1uf 600V, one across each duplex outlet/transformer secondary, and across the AC input of my DIY balanced power conditioner.
