YLED0402Y

YONGYUTAI · LED Indication - Discrete · 0402

YLED0402Y from YONGYUTAI, 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 of the yellow LED, marked pin 2 on the package drawing; reverse voltage must not exceed 5 V and the part is not designed for reverse operation.
2 A passive Anode (+) of the yellow LED, marked pin 1 with a + sign on the package drawing; DC forward current is rated 20 mA max, with a current-limiting resistor required.
