CAD (KiCad official)

  • Symbol: HY8M49SSMDOB2R20
  • Footprint: Crystal:Crystal_SMD_HC49-SD
  • 3D model: HC-49S-SMD (KiCad packages3D, STEP)
  • 3D model files: hy8m49ssmdob2r20-etched.step / hy8m49ssmdob2r20-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); hy8m49ssmdob2r20.step / hy8m49ssmdob2r20.glb are the bare package body.
