Product Overview
The XL-1608UBC-04 from XINGLIGHT is a blue SMD chip LED supplied in a 1608 surface-mount package. The package outline is 1.6 x 0.8 x 0.4 mm, with blue luminous output through a transparent colloid structure. It is categorized as an LED component and is specified with MSL 3 moisture sensitivity and RoHS Directive compliance.
At IF=20 mA and Ta=25°C, the device provides 120 to 270 mcd luminous intensity, 460 to 475 nm dominant wavelength, 465 nm typical peak wavelength, and 120° typical viewing angle. Forward voltage is specified from 2.7 to 3.4 V, with reverse current limited to <=1 uA at VR=5 V.
Assembly limits include a 260°C lead soldering condition for <=6 s, an infrared reflow limit of maximum two times, and a recommended maximum welding temperature of 240±5°C for 6 s. After opening, the package floor life is 168 hours / 7 days when stored at <=30°C and <40%RH.

Procurement Notes
When requesting a quote for XL-1608UBC-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.
