LTSA-C191KRKTA

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.

CAD (KiCad official)

  • Symbol: LTSA-C191KRKTA
  • Footprint: LED_SMD:LED_0603_1608Metric
  • 3D model: 0603 (KiCad packages3D, STEP)
  • 3D model files: ltsa-c191krkta-etched.step / ltsa-c191krkta-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ltsa-c191krkta.step / ltsa-c191krkta.glb are the bare package body.
