CAD (KiCad official)

  • Symbol: LRAN12CFTR007
  • Footprint: Resistor_SMD:R_1206_3216Metric
  • 3D model: 1206 (KiCad packages3D, STEP)
  • 3D model files: lran12cftr007-etched.step / lran12cftr007-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lran12cftr007.step / lran12cftr007.glb are the bare package body.
