The SSI-LXR3612ID is a T-3mm (T-1) red panel indicator LED featuring a red diffused epoxy lens and 835 nm peak wavelength. It delivers 30 mcd axial intensity with a 60° viewing angle (2× theta) and operates with a forward voltage of 2.0 to 2.5 Vf and a reverse voltage rating of 5.0 Vr. The device is rated for a peak forward current of 150 mA (pulse, t < 10 µs), steady-state current of 30 mA, and power dissipation of 105 mW at 25 °C, with a derating of 1.6 mW/°C above this temperature. It operates reliably across -40 °C to +85 °C and withstands soldering temperatures up to 260 °C for 3 seconds maximum at 2.0 mm from the body. This indicator is ideal for status indication, alarm signaling, and visual feedback applications in consumer electronics, industrial control panels, and instrumentation.
