CAD (KiCad official)

  • Symbol: K1210L050YR
  • Footprint: Fuse:Fuse_1210_3225Metric
  • 3D model: 1210 (KiCad packages3D, STEP)
  • 3D model files: k1210l050yr-etched.step / k1210l050yr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); k1210l050yr.step / k1210l050yr.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
