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

According to UL and other safety standards, on an AC power line you can only use "X" safety rated caps from line to line and only "Y" rated caps line to ground. Any other caps can be a fire or shock hazard and insurance companys would not cover this mis-application. "X" and "Y" rated caps are specifically designed for severe transients that can be on the line and either not fail or fail in a "safe" mode.

Agear, I did not know they were no Jensen caps in the Tripoint power conditioner. I heard about the Jensen caps in that conditioner from what Mintzar said here on the audiogon forums.

I am 100% certain that Jensen 4 pole caps are low-impedance (low ESL) caps designed for DC supplies, NOT for direct connection to AC.
Digi-Key, Mouser and Newark carry plenty of X and Y rated capacitors.
They are easier to find in the PDF catalog than through a site search.
Good luck
