I am trying to build the Schaffner line filter FN410 out of discrete parts. The datasheet for that part can be seen here: http://www.schaffner.com/corporate/...om/components/en/_pdf/Datasheet+FN410+e+6.pdf Anyways, they list all the values for the inductors and capacitors that they use in the circuit except for the inductors connected to ground. I believe they help against incoming common-mode noise. Does anybody have an idea what inductance should be use for those inductors? Thanks in advance!
