## CAD (KiCad official)

- Symbol: `CAT10-473J4LF`
- Footprint: `Resistor_SMD:R_Array_Convex_4x0402`
- 3D model: 0402x4 (KiCad packages3D, STEP)
- 3D model files: `cat10-473j4lf-etched.step` / `cat10-473j4lf-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `cat10-473j4lf.step` / `cat10-473j4lf.glb` are the bare package body.
