CAD (KiCad official)

  • Symbol: TLC-NSML300
  • Footprint: Fuse:Fuse_1206_3216Metric
  • 3D model: 1206 (KiCad packages3D, STEP)
  • 3D model files: tlc-nsml300-etched.step / tlc-nsml300-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tlc-nsml300.step / tlc-nsml300.glb are the bare package body.
