Product Overview
The XL-2012UWC-DS is a XINGLIGHT white SMD flashing LED supplied in a compact 2012 package with 2.0 x 1.2 x 0.8 mm dimensions. It is specified as a white-light device using yellow colloid/package resin and provides positive output with a power-on long flash behavior.
Electrical operation is defined over a 2.0 to 4.5 V VDD range at Ta=25°C unless otherwise defined. The datasheet lists 0.2 mA maximum operating current with no load at VDD=3 V and 20 mA typical driving current at VDS=1.0 V, VDD=3 V, Ta=25°C. Optical specifications at IF=20 mA include 500 to 900 mcd luminous intensity, 120 degree typical half-intensity viewing angle, and 6000 to 7500 K color temperature.
The part is suitable for compact white flashing LED indication where the stated voltage range, viewing angle, luminous intensity bins, and color temperature bins match the design requirement. Assembly handling is governed by MSL 3 requirements, two maximum reflow cycles, hand soldering below 30 W and under 300°C for less than 3 seconds per terminal, and specified storage, cleaning, and baking conditions.

Procurement Notes
When requesting a quote for XL-2012UWC-DS, 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.
