When examining your wurth 7448263505 common mode choke directly in hand, you may notice that the number of turns wrapped around your choke’s core doesn’t match up with the illustration shown in the datasheet.
This is fine, and will usually be the case. The purpose of this image in the datasheet is illustration only, it’s not meant to be an exact depiction of a single, specific choke. You will need to measure and test your choke to see whether it is within specification.
