CAD (KiCad official)

  • Symbol: ASMD1812-075
  • Footprint: Fuse:Fuse_1812_4532Metric
  • 3D model: 1812, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.9 mm nominal 1806 height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: asmd1812-075-etched.step / asmd1812-075-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); asmd1812-075.step / asmd1812-075.glb are the bare package body.
