Product Overview
The XL-1608UGC-04 is a XINGLIGHT emerald green SMD LED supplied in a 1608 package with 1.6 x 0.8 x 0.4 mm outline dimensions. The device uses a transparent/water colloid package and is specified as an environmental protection product complied with the RoHS Directive.
At IF=20 mA and Ta=25°C, the LED provides 350 to 1000 mcd luminous intensity, 515 to 535 nm dominant wavelength, 525 nm typical peak wavelength, 2.6 to 3.4 V forward voltage, 30 nm typical half wave width, and 120° typical viewing angle. Absolute maximum ratings include 20 mA continuous forward current, 80 mA peak forward current for pulse width <=0.1 ms and duty <=1/10, 5 V reverse voltage, and 70 mW power dissipation.
Assembly handling is defined for MSL 3 moisture sensitivity. Reflow soldering is limited to two cycles, with a recommended maximum welding temperature of 240±5°C for 6 seconds. Hand soldering is recommended only for repair or rework using an iron below 30 W, below 300°C, and less than 3 seconds per terminal.

Procurement Notes
When requesting a quote for XL-1608UGC-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.
