- [X] Silk needs to be offset from fab lines by 0.11mm as I mentioned at (comment). That will make the silk be outside the part body.

I see the problem, I only added 1 time the 0.11mm....

Updated the drawing, this is the original (F.FAB):

And 0.11mm larger for F.SilkS:

resulting in:

- [X] All symbols in Device.lib are generic so the pinout can vary or there can be multiple versions with different pinouts. However, the symbol you're showing above is outdated because it doesn't exist in the HEAD commit at https://github.com/KiCad/kicad-symbols/blob/master/Device.lib. So, if the dots on this component should be on pins 2 and 3 (or 1 and 4) using the datasheet, we can submit a new symbol with a different pinout to match. Since I'm not familiar with the convention given in the datasheet, if we can figure it out then we can match the datasheet pinout on the footprint too which I think is best. You?

--> The generic symbol with the dots is the only way of drawing a common-mode choke, in which the dots represent the input side of the filter. Because this filter contains only 2 coupled coils (I think therefore that this is the reason for the U-shape in the middle of the symbol in the datasheet) it is irrelevant which side is used as input.
I agree that it would be best to match the footprint with the pinout in the datasheet, but this would mean to create also a new symbol?
