The 591-3101-013F is a bi-color LED indicator featuring yellow and green light-emitting elements in a single 3mm prism package designed for surface-mount assembly. The device offers yellow luminous intensity of 22 mcd at 1.0 mA and green luminous intensity of 12 mcd at 1.0 mA, with forward voltages of 1.8 V typical at 2 mA for both colors. Operating over a temperature range of -40°C to +100°C, the LED supports continuous forward currents up to 15 mA and reverse voltages up to 12 V, with a peak soldering temperature of 245°C. The yellow LED exhibits a peak wavelength of 591 nm, while the green LED peaks at 572 nm, making this component ideal for status indication, alarm signaling, and multi-state visual feedback applications in industrial and consumer electronics.
