During troubleshooting in test lab, it is tempting to be quick and connect filter solutions with soldering and some wires.
Instead, you should probably lay out components on a pcb and get it as it is described in the books. But in practice, at the test lab, you can't do that and the question is how messy can such an EMI filter be? How long can the wires between CM chokes, capacitors be and when you don't solder but use Wago-connectors for interconnection, is it so that the filter is almost already destroyed by the impedance that you have no control over? As we get up in frequency (conducted emission 150kH-30MHz), messy design / connection will get more worse when frequency increase, but we will get trouble anyway in the 150kH-30MHz range. At least from 1MHz. Right? BR Amund - ---------------------------------------------------------------- This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
