NCD0402W1

Foshan NationStar Optoelectronics · LED Indication - Discrete · 0402

NCD0402W1 from Foshan NationStar Optoelectronics, in a 0402. 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 (negative terminal) of the LED, identified by the cathode mark on the package; reverse voltage must not exceed 5 V and forward current is limited to 20 mA continuous (50 mA pulsed).
2 A passive Anode (positive terminal) of the LED; typical forward voltage is 2.8 V (2.5 V min, 3.6 V max) at IF=5 mA, with forward current limited to 20 mA continuous (50 mA pulsed).
