Product Overview
The XL-1608SURC-04 is a XINGLIGHT red SMD LED built in a compact 1608 outline. Its package dimensions are 1.6 x 0.8 x 0.4 mm, with a general dimension tolerance of ±0.25 mm unless otherwise noted. The luminous color is red with transparent/water colloid construction, and the component is identified as moisture sensitivity level MSL 3.
At IF=20 mA and Ta=25°C, the LED is specified for 80-120 mcd luminous intensity, 620-625 nm dominant wavelength, 625 nm typical peak wavelength, 1.9-2.1 V forward voltage, 20 nm typical half wave width, and 120° typical viewing angle. Reverse current is limited to <=1 µA at VR=5 V and Ta=25°C.
Absolute maximum ratings include 50 mW power dissipation, 20 mA continuous forward current, 80 mA peak forward current for pulse width <=0.1 ms and duty <=1/10, 5 V reverse voltage, and 2000 V ESD withstand voltage at Ta=25°C. Assembly guidance includes reflow soldering up to two cycles, a recommended maximum welding temperature of 240±5°C for 6 s, and controlled post-solder cleaning conditions.

Procurement Notes
When requesting a quote for XL-1608SURC-04, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For LED and optoelectronic sourcing, brightness bin, wavelength or color temperature bin, forward voltage range, viewing angle, moisture sensitivity level and soldering process limits may affect final selection, availability and lead time.
