## CAD (KiCad official)

- Symbol: `YLED1206W`
- Footprint: `LED_SMD:LED_1206_3216Metric`
- 3D model: 1206 (KiCad packages3D, STEP)
- 3D model files: `yled1206w-etched.step` / `yled1206w-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `yled1206w.step` / `yled1206w.glb` are the bare package body.
