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. |
