Footprint and pin 1
The part is not polarized electrically. Pad 1 is the start of the winding, marked by the dot on the top of the part (datasheet p.1 product marking). The footprint puts pad 1 on the left, matching Würth's own KiCad footprint L_Wurth_WE-XHMI-6060, with a silkscreen dot below pad 1. Keep vias and sensitive traces out from under the part (datasheet land pattern note).
Land pattern source: p.1 'Recommended Land Pattern [mm]': pads 5.5 x 1.45, gap 2.55 -> pad centres x = +-2.00 mm; 'no vias and sensitive traces underneath the component'.
Pads: 2 x 1.45 x 5.5 mm at x = -2.0 and +2.0 mm (2.55 mm gap), the datasheet's recommended land pattern; identical to Würth's own KiCad footprint L_Wurth_WE-XHMI-6060.
3D models
The model is Würth Elektronik's own L_Wurth_WE-XHMI-6060 from its KiCad library (CC BY-SA 4.0), modified by Adom: a header note marks it as modified and names the original, and the -etched variant adds the virtual MPN mark. Geometry, pose and colours are Würth's. It is Z-up with the terminals on z = 0. Würth's model carries a placeholder engraving 'Marking' on the top, so the MPN mark sits on a side wall. The product-page STEP download is not published here because it carries no licence text.

Plain model |
74439346047-etched.step / 74439346047-etched.glb |
The same model with the MPN as a virtual laser mark (side face, adom-aiflow-etch, gate PASS). This is the board/library model. |
74439346047-hero.glb |
The page's 3D view: the marked model plus teal dashed pad outlines, silkscreen with pin 1 and signal names (adom-hero 1.4). Not for boards. |
The MPN mark is an identification aid added by Adom, not a claim about the manufacturer's real marking.
