## CAD (KiCad official)

- Symbol: `YSMC201208H-2R2MB`
- Footprint: `Inductor_SMD:L_0805_2012Metric`
- 3D model: 0805 (KiCad packages3D, STEP)
- 3D model files: `ysmc201208h-2r2mb-etched.step` / `ysmc201208h-2r2mb-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ysmc201208h-2r2mb.step` / `ysmc201208h-2r2mb.glb` are the bare package body.
