CAD (KiCad official)

  • Symbol: RN73H1ETTP2003B25
  • Footprint: Resistor_SMD:R_0402_1005Metric
  • 3D model: 0402 (KiCad packages3D, STEP)
  • 3D model files: rn73h1ettp2003b25-etched.step / rn73h1ettp2003b25-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); rn73h1ettp2003b25.step / rn73h1ettp2003b25.glb are the bare package body.
