## CAD (KiCad official)

- Symbol: `SX25Y026000BC1T001`
- Footprint: `Crystal:Crystal_SMD_2520-4Pin_2.5x2.0mm`
- 3D model: SMD2520-4P (KiCad packages3D, STEP)
- 3D model files: `sx25y026000bc1t001-etched.step` / `sx25y026000bc1t001-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `sx25y026000bc1t001.step` / `sx25y026000bc1t001.glb` are the bare package body.
