Product Overview
The XL-3528UOC is an orange SMD LED from XINGLIGHT supplied in a 3528 surface-mount package. The package dimensions are 3.5 x 2.8 x 1.9 mm, with a water-clear transparent colloid over the orange emitter. The part is identified as suitable for SMT automatic production and is specified with a dimension tolerance of ±0.25 mm unless otherwise noted.
At IF=20 mA and Ta=25°C, the LED provides 300 to 400 mcd luminous intensity, 600 to 608 nm dominant wavelength, 605 nm typical peak wavelength, and 1.8 to 2.4 V forward voltage. The typical viewing angle is 120°, with a 20 nm typical half-wave width and reverse current of <=5 µA at VR=5 V.
Assembly and handling data include MSL 3 classification, RoHS compliance, lead-free reflow peak temperature of 255°C +0/-5°C for 5 to 10 s, and a maximum of two reflow cycles. Storage guidance specifies unopened storage at <=30°C and <60% RH for use within one year, and opened storage at <=30°C and <40% RH with soldering within 168 hours.
