Product Overview
The XL-3528UYC is a XINGLIGHT yellow SMD LED supplied in a 3528 surface-mount package. Its outline dimensions are 3.5 x 2.8 x 1.9 mm, and the luminous color is yellow with a transparent/water-clear colloid construction. The part is listed as compliant with the RoHS Directive and has a moisture sensitivity level of MSL 3.
At IF=20 mA and Ta=25°C, the LED is specified for 270-450 mcd luminous intensity, 585-595 nm dominant wavelength, 588 nm typical peak wavelength, 1.8-2.4 V forward voltage, 120° typical viewing angle, and 20 nm typical half wave width. Reverse current is specified as <=5 µA at VR=5 V and Ta=25°C.
Assembly and storage limits include maximum 2 reflow cycles, a recommended maximum welding temperature of 240±5°C for 6 seconds, and hand soldering below 300°C for less than 3 seconds per terminal. Storage guidance specifies <=30°C and <=60%RH before opening within 1 year, and <=30°C and <=40%RH after opening with soldering within 168 hours / 7 days.

Procurement Notes
When requesting a quote for XL-3528UYC, 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.
