CAD (KiCad official)

  • Symbol: BLM15HB221SZ1D
  • Footprint: Inductor_SMD:L_0402_1005Metric
  • 3D model: 0402 (KiCad packages3D, STEP)
  • 3D model files: blm15hb221sz1d-etched.step / blm15hb221sz1d-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); blm15hb221sz1d.step / blm15hb221sz1d.glb are the bare package body.
