Product Overview
XL-2012UWC-DS is a XINGLIGHT white flashing SMD LED supplied in a 2012 surface-mount package. The appearance dimensions are 2.0 x 1.2 x 0.8 mm, with outline dimensional tolerance of ±0.25 mm unless otherwise noted. The device is specified as white light with yellow colloid and provides positive output with power-on long flash behavior.
Electrical operation is defined over a 2.0-4.5 V VDD range at Ta=25°C unless otherwise defined. Operating current is specified at a maximum of 0.2 mA with VDD=3 V and no load, while driving current is typically 20 mA at VDS=1.0 V. Optical data at IF=20 mA includes 500-900 mcd luminous intensity, 6000-7500 K color temperature, and a typical 120 degree half-intensity viewing angle.
Assembly and storage controls are part of the device requirements. The LED is MSL 3, supports a maximum of two reflow soldering passes, and has a recommended maximum soldering temperature of 240 ± 5°C for 6 seconds. After opening, storage is limited to ≤30°C and ≤40% RH with soldering within 168 hours / 7 days.

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.
