The SML-LX1206IC-TR is a surface-mount red LED designed for indicator and display applications in compact electronic assemblies. It features a peak wavelength of 640 nm with a typical luminous intensity of 9 mcd at 20 mA forward current, a wide 130° viewing angle (2× theta1/2), and a water-clear epoxy lens for optimal light transmission. The device operates with a forward voltage of 2.0 to 2.4 V at 20 mA, a maximum reverse current of 10 µA at 5 V reverse bias, and is rated for -40 °C to +85 °C operating temperature with a maximum power dissipation of 100 mW. The 1206 form factor (3.2 × 1.5 × 1.0 mm) enables high-density PCB integration, and the device is supplied in tape and reel packaging (2000 pcs/reel) with RoHS compliance and halogen-free construction, making it suitable for consumer electronics, automotive instrumentation, and industrial control panels.
