CAD (KiCad official)

  • Symbol: FR103W F3
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123FL (KiCad packages3D, STEP)
  • 3D model files: fr103w-f3-etched.step / fr103w-f3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); fr103w-f3.step / fr103w-f3.glb are the bare package body.
