CAD (KiCad official)

  • Symbol: 3438T-32.768DTTLNNL
  • Footprint: Crystal:Crystal_C38-LF_D3.0mm_L8.0mm_Vertical
  • 3D model: DT-38 (KiCad packages3D, STEP)
  • 3D model files: 3438t-32-768dttlnnl-etched.step / 3438t-32-768dttlnnl-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 3438t-32-768dttlnnl.step / 3438t-32-768dttlnnl.glb are the bare package body.
