Yongyu Photoelectric · LED Indication - Discrete · 0402
SZYY0402Y from Yongyu Photoelectric, 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; the reverse voltage across the LED must not exceed 5 V. |
| 2 | A | passive | Anode (+) of the yellow LED; forward current is rated at 25 mA DC (60 mA peak at 1/10 duty, 0.1 ms) and VF is 1.8 to 2.4 V at IF=10 mA. |
