11-21UYC

Everlight Elec · LED Indication - Discrete · 1206

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.
