YLED0402YG

YONGYUTAI · LED Indication - Discrete · 0402

YLED0402YG 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 terminal marked ② in the package drawing; reverse voltage must not exceed 5 V, and the part is not designed for reverse operation.
2 A passive Anode (+) terminal marked ① in the package drawing; drive at the rated DC forward current of 20 mA (60 mA peak at 1/10 duty, 0.1 ms) through a series current-limiting resistor.

CAD (KiCad official)

  • Symbol: YLED0402YG
  • Footprint: LED_SMD:LED_0402_1005Metric
  • 3D model: 0402 (KiCad packages3D, STEP)
  • 3D model files: yled0402yg-etched.step / yled0402yg-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); yled0402yg.step / yled0402yg.glb are the bare package body.
