11-21UYC from Everlight Elec, in a 1206. 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 LED, marked by the cathode mark on the package; reverse voltage VR max 5 V (IR test only, not designed for reverse operation). |
| 2 | A | passive | Anode (+) of the LED; forward current IF max 25 mA, forward voltage 2.0 V typ / 2.4 V max at IF=20 mA, requires a series resistor for current limiting. |
