## CAD (KiCad official)

- Symbol: `K383276812510`
- Footprint: `Crystal:Crystal_C38-LF_D3.0mm_L8.0mm_Vertical`
- 3D model: DT-38 (KiCad packages3D, STEP)
- 3D model files: `k383276812510-etched.step` / `k383276812510-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `k383276812510.step` / `k383276812510.glb` are the bare package body.
