## CAD (KiCad official)

- Symbol: `BAT30F4`
- Footprint: `Resistor_SMD:R_0201_0603Metric`
- 3D model: 0201 (KiCad packages3D, STEP)
- 3D model files: `bat30f4-etched.step` / `bat30f4-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `bat30f4.step` / `bat30f4.glb` are the bare package body.
