CAD (KiCad official)

  • Symbol: NT04105F3950B1F
  • Footprint: Resistor_SMD:R_0402_1005Metric
  • 3D model: 0402 (KiCad packages3D, STEP)
  • 3D model files: nt04105f3950b1f-etched.step / nt04105f3950b1f-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); nt04105f3950b1f.step / nt04105f3950b1f.glb are the bare package body.
