Hi BiBo01,I use these Epcos filters because the are readily available and not very expensive.
But many others company's manufacture same types.Epcos EMC Filters Series/Type: B84111A
See http://www.mouser.com/ds/2/400/b84111a-773410.pdf
(Since 2013 Epcos stopt production.)On the ATX PSU power line I put a filter which can handle 3A amps.
2 years ago I still used active Klein & Hummel O300 monitors which have 3 amplifiers build inside with a total max consumption of 435 Watts per speaker. Sow on the power lines too the K&H O300 I put an Epcos (6A amps rating) reversed (line side now is: side with the caps)
You find the schematic's all over the www and they are used by many other filter company's like Schurter, etc.
I first saw the schematic's discussed in Ivor Catt e.a. book Digital Hardware Design, by Ivor Catt, David Walton, Malcolm Davidson.
http://www.ivorcatt.org/digital-hardware-design.htm
Chapter 14 page 84 and on.The Epcos filters I use have a standard, generic design which does not filter the ground-wire.
So depending on where the noise source is located, the ground-wire may still facilitate loops.Mark
