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/en/register_log.asp?language_id=12&fN=http%3A%2F%2Fwww%2Eschaffner%2Ecom%2Fcomponents%2Fen%2F%5Fpdf%2FDatasheet+FN410+e+6%2Epdf [Broken] 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!
