LTST-C191KEKT

Lite-On · LED Indication - Discrete · 0603

LTST-C191KEKT 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, the notched-pad end marked CATHODE on the package drawing; the datasheet gives a 5 V maximum reverse voltage.
2 A passive Anode soldering terminal (+ polarity); the datasheet gives a 30 mA maximum DC forward current, 80 mA peak (1/10 duty, 0.1 ms) and a typical VF of 2.0 to 2.4 V at IF = 20 mA.
