can mundorf supreme caps be used for AC filtering


Hi I have some mundorf supreme caps rated at [.047] 600v , can these be safely used in AC filtering without fire risk ? I know that shunyata and audience use cap filtering in there line conditioning products. between negative and positive, not ground. thanks, Chris

anybody ???? the point is I already have 8 .47 mundorf supreme caps and love a good project, i might get some lager mundorfs and bypass them with the ones I already have, and make My own filter, but I dont know if this will limit current to my amps or not , thanks ,chris
no. no current limiting in AC filters other than trannys & inductors. my fave conditioners use neither.

also, suspect that putting caps from H/N to ground would also help. but do more research.

also, may want to encapsulate the caps in flameproof heatshrink, just in case
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.
thanks gbart, I know that the mundorfs are ac rated . what value auricaps did you use? how many ? thanks, chris
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.
