Product Overview
XL-1608UWC-06 is a XINGLIGHT white SMD LED supplied in a compact 1608 surface-mount package with 1.6 x 0.8 x 0.6 mm outline dimensions. The datasheet identifies the luminous color as white light and the colloid or lens appearance as yellow mist, with main color area options C1 for product code CW5-21 and C0 for product code CW4-20.
At IF=20 mA and Ta=25°C, the device is specified for 360-1000 mcd luminous intensity, 10000-25000 K color temperature, 2.6-3.4 V forward voltage, and a 120° viewing angle. Reverse current is limited to 1 μA maximum at VR=5 V. Absolute maximum ratings include 75 mW power dissipation, 20 mA continuous forward current, 80 mA peak forward current under pulsed conditions, and 5 V maximum reverse voltage.
Assembly data covers EIA standard packaging for SMT automatic production, MSL 3 handling, reflow limits, hand soldering restrictions, cleaning limits, and storage conditions. These parameters suit compact indicator and backlight positions where a small white SMD LED with defined binning and soldering controls is required.

Procurement Notes
When requesting a quote for XL-1608UWC-06, 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.
