Common mode choke SRF should selected to be at the worst case EMC problem frequency?
Hi,
The following is an app note on use of common mode chokes to improve EMC….
https://www.schaffner.com/fileadmin...ation_note/Schaffner_AN_RB_common_chockes.pdf
Nowhere in this app note does it mention the self resonant frequency of the common mode choke.
Do you know why this is?
Surely THE big thing about use of common mode chokes in EMC , is that the SRF of the common mode choke should be placed at the worst case common mode EMC problem frequency?
