CAD (KiCad official)

  • Symbol: DFE21CCNR47MELL
  • Footprint: Inductor_SMD:L_0805_2012Metric
  • 3D model: 0805 (KiCad packages3D, STEP)
  • 3D model files: dfe21ccnr47mell-etched.step / dfe21ccnr47mell-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dfe21ccnr47mell.step / dfe21ccnr47mell.glb are the bare package body.
