CAD (KiCad official)

  • Symbol: F12T7
  • Footprint: Fuse:Fuse_1206_3216Metric
  • 3D model: 1206 (KiCad packages3D, STEP)
  • 3D model files: f12t7-etched.step / f12t7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); f12t7.step / f12t7.glb are the bare package body.
