7499111121A

"""AI-created simplified 3D model of Wurth Elektronik 7499111121A (WE-RJ45LAN, RJ45 tab down with
integrated 10/100/1000BASE-T magnetics, yellow/green LEDs, shielded, THT), built from the Wurth
datasheet 7499111121A rev 003.000 page 1 (body 16.0 x 21.25 x 13.5, pin length 3.5 +-0.5 below the
PCB, recommended hole pattern: 10 x d0.9 signal, 4 x d1.03 LED, 2 x d1.6 shield, 2 x d3.25 posts).

Frame: Adom Z-up, millimetres, seating plane z = 0, origin = body centre (footprint origin).
Model y = -(KiCad y); the RJ45 opening faces model -y (front edge y = -10.625). Seen from the front,
looking into the port, the yellow LED (pins 11/12) is on the left and the green LED (13/14) on the right.

Simplifications: the shield is a closed sheet-metal box with the port opening; the RJ45 cavity is a
plain rectangular opening with the latch slot at the bottom (tab down); LED light pipes are drawn as
translucent blocks at the lower front corners; no panel EMI fingers, no internal contacts; pins are
straight round posts.
