## CAD (KiCad official)

- Symbol: `BLM15AG102SN1D11`
- Footprint: `Inductor_SMD:L_0402_1005Metric`
- 3D model: 0402 (KiCad packages3D, STEP)
- 3D model files: `blm15ag102sn1d11-etched.step` / `blm15ag102sn1d11-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `blm15ag102sn1d11.step` / `blm15ag102sn1d11.glb` are the bare package body.
