## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | K | passive | Cathode terminal, marked by the cathode line and cathode mark on the package; the datasheet gives 5 V maximum reverse voltage (IR = 100 µA). |
| 2 | A | passive | Anode terminal, the unmarked soldering terminal of the 2-terminal chip LED; the datasheet gives 20 mA maximum DC forward current and typical VF of 3.4 V at 20 mA. |

## CAD (KiCad official)

- Symbol: `HSMR-C190`
- Footprint: `LED_SMD:LED_0603_1608Metric`
- 3D model: 0603 (KiCad packages3D, STEP)
- 3D model files: `hsmr-c190-etched.step` / `hsmr-c190-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `hsmr-c190.step` / `hsmr-c190.glb` are the bare package body.
