LTW-C191TS5 from Lite On, in a 0603. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | K | passive | Cathode (-) soldering terminal, marked with the cathode indicator on the package, and the reverse voltage across the LED must not exceed 5 V. |
| 2 | A | passive | Anode (+) soldering terminal of the InGaN white LED, driven through a series current-limiting resistor with DC forward current up to 20 mA (100 mA peak at 1/10 duty, 0.1 ms) and VF 2.70 to 3.15 V at IF = 5 mA. |
