CAD (KiCad official)

  • Symbol: 043501.5KRHF
  • Footprint: Fuse:Fuse_0402_1005Metric
  • 3D model: 0402 (KiCad packages3D, STEP)
  • 3D model files: 043501-5krhf-etched.step / 043501-5krhf-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 043501-5krhf.step / 043501-5krhf.glb are the bare package body.
