Product Overview
XL-2012WYC is a XINGLIGHT yellow SMD LED supplied in a 2012 surface-mount package with 2.0 x 1.2 x 0.8 mm outline dimensions. The datasheet identifies the component as a yellow-light LED with yellow colloid, RoHS directive compliance, and moisture sensitivity level MSL 3.
At IF=20 mA and Ta=25°C, the LED is specified for 350 to 1000 mcd luminous intensity, 2.7 to 3.4 V forward voltage, chromaticity coordinate X of 0.4752 to 0.5428, chromaticity coordinate Y of 0.4060 to 0.4816, and 120° typical viewing angle. Absolute maximum ratings include 70 mW power dissipation, 20 mA continuous forward current, 80 mA peak forward current for pulse width <=0.1 ms and duty <=1/10, and 5 V reverse voltage.
Assembly guidance includes 260°C lead soldering for <=6 s, recommended maximum reflow temperature of 240 ±5°C for 6 s, and a maximum of two reflow soldering cycles. Storage controls specify <=30°C and <60% RH before opening, and soldering within 168 hours after opening at <=30°C and <40% RH.

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