APT1608LSECK

Kingbright · LED Indication - Discrete · 0603

APT1608LSECK from Kingbright, 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 of the LED, shown as pin 2 in the package drawing symbol and located on the polarity-mark side (reverse voltage max 5 V).
2 A passive Anode terminal of the Hyper Red AlGaInP LED, shown as pin 1 in the package drawing symbol (VF 1.8 V typ, 2.1 V max at IF = 2 mA; DC forward current max 30 mA).
