Product Overview
XL-1606UYC is a XINGLIGHT high brightness yellow SMD LED supplied in a 1.7 x 0.6 x 1.1 mm package. The device is described with a transparent/water colloid package and meets RoHS requirements. It is an LED component intended for compact surface-mount layouts where yellow indication and a small package outline are required.
At IF=20 mA and Ta=25°C, the LED provides 80 to 210 mcd luminous intensity, 585 to 595 nm dominant wavelength, and 590 nm typical peak wavelength. The forward voltage range is 1.8 to 2.4 V under the same test condition, with a 120° typical viewing angle and reverse current of no more than 5 µA at VR=5 V.
Assembly and handling limits include MSL 3, a maximum of two reflow cycles, recommended maximum welding temperature of 240±5°C for 6 s, and hand soldering below 300°C for less than 3 s per terminal. Storage guidance specifies unopened storage at <=30°C and <60% RH for use within one year, and soldering within 168 hours after opening at <=30°C and <40% RH.

Procurement Notes
When requesting a quote for XL-1606UYC, 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.
