Lite On · LED Indication - Discrete · 0603
LTSA-C191KRKTA 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 (-) terminal, marked by the cathode mark on the package; reverse current is at most 10 uA at VR = 5 V and the device is not designed for reverse operation. |
| 2 | A | passive | Anode (+) terminal of the AlInGaP super red LED; forward voltage 1.60 V min to 2.60 V max at IF = 20 mA, DC forward current rating 30 mA. |
