Product Overview
XL-2012UYC is a XINGLIGHT yellow SMD chip LED supplied in a compact 2012 surface-mount package. The outline dimensions are 2.0 x 1.2 x 0.8 mm, with a transparent/water colloid structure for the yellow LED.
At IF=20 mA and Ta=25°C, the device is specified for 80 to 210 mcd luminous intensity, 585 to 595 nm dominant wavelength, 590 nm typical peak wavelength, 1.8 to 2.4 V forward voltage, 20 nm typical half wave width, and 120° typical viewing angle. Absolute maximum ratings include 50 mW power dissipation, 20 mA continuous forward current, 80 mA peak forward current under pulsed conditions, and 5 V maximum reverse voltage.
Assembly and handling data include MSL 3 classification, RoHS compliance, 260°C lead soldering for up to 6 seconds, recommended reflow at 240 ±5°C for 6 seconds, and a maximum of two reflow cycles. Storage guidance specifies unopened storage at <=30°C and <60% RH within one year, or soldering within 168 hours after opening at <=30°C and <40% RH.

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