Product Overview
XL-3528UBC is a XINGLIGHT blue surface-mount LED supplied in a 3528 SMD outline. The package dimensions are 3.5 x 2.8 x 1.9 mm with a stated outline tolerance of ±0.25 mm, and the optical structure uses a water-clear transparent colloid lens. The device emits blue light with a 455-470 nm dominant wavelength and a 465 nm typical peak wavelength at IF=20 mA and Ta=25°C.
Electrical and optical parameters include 400-550 mcd luminous intensity, 2.8-3.4 V forward voltage, 120° typical viewing angle, and 25 nm typical half-wave width under the stated 20 mA test condition. Absolute maximum ratings include 70 mW power dissipation, 20 mA continuous forward current, 80 mA peak forward current under pulse conditions, 5 V maximum reverse voltage, and 2000 V ESD rating.
For assembly, XL-3528UBC is suitable for SMT automatic production and infrared reflow soldering. The datasheet lists lead-free reflow parameters, a maximum of two reflow cycles, MSL 3 handling, EIA standard packaging, and storage or baking conditions for moisture control.

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