Product Overview
XL-2835UWC-1W is a XINGLIGHT white SMD LED built in a 2835 package. The package outline is 2.8 x 3.5 x 0.8 mm, with yellow colloid construction for white-light output. The datasheet identifies the part as an LED with white luminous color, MSL 3 moisture sensitivity, and RoHS directive compliance.
At IF=350 mA and Ta=25°C, the device is specified for 100-130 lm luminous flux, 6000-7500 K color temperature, and 2.8-3.4 V forward voltage. The typical viewing angle is 120 deg at IF=150 mA. Absolute maximum ratings include 350 mA continuous forward current, 500 mA peak forward current under pulsed conditions, 5 V maximum reverse voltage, 1000 mW maximum power dissipation, and 2000 V ESD rating.
Assembly data includes 260°C soldering for up to 6 s, two maximum reflow cycles, lead-free reflow peak temperature of 255°C +0/-5°C, and recommended workshop storage of <=30°C and <60% RH after opening. Typical use cases include white LED illumination and compact SMD lighting assemblies.

Procurement Notes
When requesting a quote for XL-2835UWC-1W, 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.
