In Reply to: The problem with big, honking filter capacitors posted by Al Sekela on May 12, 2008 at 13:49:08:
As Andy already rightly pointed out: paralleling the large caps with much higher self resonant frequency low ESR(usually much smaller package size) parts along with using an appropriate power and ground plane will allow excellent filtering up into the GHz range. Obviously the honking caps are meant for the low frequency disturbances not the high frequency ones but since apparently low and high frequency problems are present we need both. The good news is since these GHz frequencies are likely mostly going to be generated externally to the boxes I own and not internally they will be very filterable from entering the box in the first place by using what I would consider low footprint low cost filters such as your own powerline RC's not to mention the big trannys in most of my equipments power supplies wont pass these signals very well even if they are present at the primaries.
