CAD (KiCad official)

  • Symbol: BLM21BD182SN1D
  • Footprint: Inductor_SMD:L_0805_2012Metric
  • 3D model: 0805 (KiCad packages3D, STEP)
  • 3D model files: blm21bd182sn1d-etched.step / blm21bd182sn1d-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); blm21bd182sn1d.step / blm21bd182sn1d.glb are the bare package body.
