## CAD (KiCad official)

- Symbol: `RC3134KM3`
- Footprint: `Package_TO_SOT_SMD:SOT-723`
- 3D model: SOT-723, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.5 mm nominal SOT-723 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: `rc3134km3-etched.step` / `rc3134km3-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `rc3134km3.step` / `rc3134km3.glb` are the bare package body.
