CAD (KiCad official)

  • Symbol: 49SS-25.00-20-10-10
  • Footprint: Crystal:Crystal_HC49-4H_Vertical
  • 3D model: HC-49S (KiCad packages3D, STEP)
  • 3D model files: 49ss-25-00-20-10-10-etched.step / 49ss-25-00-20-10-10-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 49ss-25-00-20-10-10.step / 49ss-25-00-20-10-10.glb are the bare package body.
