The classic cap in this application is silver mica. High voltage capacity, super tolerance compared to other types (to 0.25%! but commonly 1% or 2%). The only ones I have are enormous bulky things with "dot" style marking. A quick search on Mouser turns up only SMT ones... > My best bet is to use X7R capacitors with as much DC voltage rating as I can > get. I don't know if there's any connection between the DC and AC losses. Not X7R. -- Ben Jackson AD7GD <b...@ben.com> http://www.ben.com/ _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
