Go ahead and put it on the pwb. We do it anf it works very well. There is a caveat though - pay a lot of attention to the layout and final installation.

Why is this enclosure required? Are there specific provisions in the standards? My idea is to build up the filter circuit on a printed circuit board and make it an integral part of the power supply. I am currently looking at EN133200 which has certain seal tests but after reviewing these, they all appear to be related to climatic or environmental conditions. If the product passes these tests without the enclosure it would seem that the product has passed, period. Alternatively I have considered removing the nomenclature "EMI filter" and simply call it an input module, then evaluate it as a part of the overall system. If it passes the EMC and Product Safety requirements, can I call the job complete? Any thoughts? ======================================= Douglas E.
