CAD (KiCad official)

  • Symbol: SWXSHBCVE0-25.000000
  • Footprint: Crystal:Crystal_HC49-4H_Vertical
  • 3D model: HC-49S (KiCad packages3D, STEP)
  • 3D model files: swxshbcve0-25-000000-etched.step / swxshbcve0-25-000000-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); swxshbcve0-25-000000.step / swxshbcve0-25-000000.glb are the bare package body.
