The SML-LX0402SYC-TR is a 1.0 mm × 0.5 mm surface-mount LED indicator emitting super yellow light at a peak wavelength of 590 nm with a water-clear epoxy lens. It delivers a typical axial intensity of 60 mcd at 20 mA forward current with a wide 120° viewing angle (2× theta), and features a forward voltage of 2.0 to 2.5 V and a reverse voltage rating of 5.0 V. The device is rated for a steady current of 30 mA maximum, peak forward current of 160 mA (pulse duration <10 µs), and power dissipation of 125 mW with a derating of -1.2 mW/°C above 25 °C. Operating and storage temperature ranges are -40 °C to +85 °C, and the component is moisture-sensitive per JEDEC Level 3 standards. This compact LED is ideal for status indication, backlighting, and visual feedback applications in consumer electronics, industrial control panels, and portable devices where space is constrained.
