## CAD (KiCad official)

- Symbol: `1812L600SL16GRG`
- Footprint: `Fuse:Fuse_1812_4532Metric`
- 3D model: 1812, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.9 mm nominal _1806_ height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
- 3D model files: `1812l600sl16grg-etched.step` / `1812l600sl16grg-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `1812l600sl16grg.step` / `1812l600sl16grg.glb` are the bare package body.
