CAD (KiCad official)

  • Symbol: RL0805A390K
  • Footprint: Resistor_SMD:R_0805_2012Metric
  • 3D model: 0805 (KiCad packages3D, STEP)
  • 3D model files: rl0805a390k-etched.step / rl0805a390k-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); rl0805a390k.step / rl0805a390k.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
