## CAD (KiCad official)

- Symbol: `CFS20632768EZFB`
- Footprint: `Crystal:Crystal_DS26_D2.0mm_L6.0mm_Vertical`
- 3D model: DT-26 (KiCad packages3D, STEP)
- 3D model files: `cfs20632768ezfb-etched.step` / `cfs20632768ezfb-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `cfs20632768ezfb.step` / `cfs20632768ezfb.glb` are the bare package body.
