## CAD (KiCad official)

- Symbol: `YLED0603YG`
- Footprint: `LED_SMD:LED_0603_1608Metric`
- 3D model: 0603, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.5 mm nominal _0603_ height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
