Product Overview
XINGLIGHT XL-1608UWC-04 is a cool white surface-mount LED built in a 1608 package with 1.6 x 0.8 x 0.6 mm outline dimensions. The device uses a yellow mist colloid appearance and is specified as a cool white light LED, with color temperature from 10000 K to 33000 K at IF=20 mA and Ta=25°C.
Electrical and optical ratings include 20 mA maximum continuous forward current, 80 mA peak forward current under pulse conditions of pulse width <=0.1 ms and duty <=1/10, 75 mW maximum power dissipation, and 5 V maximum reverse voltage. At IF=20 mA, the forward voltage range is 2.6 to 3.4 V, luminous intensity is 400 to 1000 mcd, and the typical viewing angle is 120°.
Assembly data includes MSL 3 moisture sensitivity, 168 hours / 7 days opened-package floor life at <=30°C and <40%RH, recommended maximum reflow soldering of 240±5°C for 6 s, and up to two reflow soldering cycles. The compact cool white output suits indicator, backlight, and small illumination positions where a 1608 SMD LED footprint is required.

Procurement Notes
When requesting a quote for XL-1608UWC-04, 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.
