LTST-C190KFKT

Lite On · LED Indication - Discrete · 0603

LTST-C190KFKT 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, marked CATHODE on the package drawing with the notched T-shaped pad, forward voltage 2.0 to 2.4 V at IF = 20 mA.
2 A passive Anode (+) soldering terminal of the AlInGaP orange LED, driven through a series current-limiting resistor with DC forward current up to 30 mA and reverse voltage up to 5 V.
