## CAD (KiCad official)

- Symbol: `XRNR252010-3.3uH`
- Footprint: `Inductor_SMD:L_1008_2520Metric`
- 3D model: 1008 (KiCad packages3D, STEP)
- 3D model files: `xrnr252010-3-3uh-etched.step` / `xrnr252010-3-3uh-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `xrnr252010-3-3uh.step` / `xrnr252010-3-3uh.glb` are the bare package body.
