Symbol: RN1105MFV
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: rn1105mfv-etched.step / rn1105mfv-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); rn1105mfv.step / rn1105mfv.glb are the bare package body.
