LTST-C191TBKT

Lite On · LED Indication - Discrete · 0603

LTST-C191TBKT 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); negative side of the polarity symbol, DC forward current max 20 mA.
2 A passive Anode terminal, the positive (+) side of the polarity symbol on the package drawing; forward voltage 2.80 to 3.80 V at IF = 20 mA, DC forward current max 20 mA.
