## CAD (KiCad official)

- Symbol: `BLM18HE152SN1D`
- Footprint: `Inductor_SMD:L_0603_1608Metric`
- 3D model: 0603 (KiCad packages3D, STEP)
- 3D model files: `blm18he152sn1d-etched.step` / `blm18he152sn1d-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `blm18he152sn1d.step` / `blm18he152sn1d.glb` are the bare package body.
