## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | K | passive | Cathode (marked "-" in the polarity diagram); for the white IN-S42BT5UW, IF is 25 mA max, typical VF 3.2 V and max 3.6 V at 5 mA, VR 5 V max. |
| 2 | A | passive | Anode (marked "+" in the polarity diagram); for the white IN-S42BT5UW, IF is 25 mA max, IFP is 100 mA (1/10 duty, 0.1 ms pulse), typical VF 3.2 V and max 3.6 V at 5 mA. |

## CAD (KiCad official)

- Symbol: `IN-S42BT5UW`
- Footprint: `LED_SMD:LED_0402_1005Metric`
- 3D model: 0402 (KiCad packages3D, STEP)
- 3D model files: `in-s42bt5uw-etched.step` / `in-s42bt5uw-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `in-s42bt5uw.step` / `in-s42bt5uw.glb` are the bare package body.
