LTST-C191KFKT

Lite On · LED Indication - Discrete · 0603

LTST-C191KFKT 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 CATHODE on the package drawing (the terminal with the notched pad shape); reverse voltage 5 V test limit with IR max 10 uA.
2 A passive Anode (+) terminal of the AlInGaP orange LED; drive through a series current-limiting resistor, DC forward current max 30 mA, VF 2.0 V min to 2.4 V max at IF = 20 mA.

CAD (KiCad official)

  • Symbol: LTST-C191KFKT
  • Footprint: LED_SMD:LED_0603_1608Metric
  • 3D model: 0603 (KiCad packages3D, STEP)
  • 3D model files: ltst-c191kfkt-etched.step / ltst-c191kfkt-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ltst-c191kfkt.step / ltst-c191kfkt.glb are the bare package body.
