CAD (KiCad official)

  • Symbol: 0440005.WR
  • Footprint: Fuse:Fuse_1206_3216Metric
  • 3D model: 1206 (KiCad packages3D, STEP)
  • 3D model files: 0440005-wr-etched.step / 0440005-wr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 0440005-wr.step / 0440005-wr.glb are the bare package body.
