CAD (KiCad official)

  • Symbol: SL1210450
  • Footprint: Fuse:Fuse_1210_3225Metric
  • 3D model: 1210 (KiCad packages3D, STEP)
  • 3D model files: sl1210450-etched.step / sl1210450-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sl1210450.step / sl1210450.glb are the bare package body.
