Product Overview
XL-TD1608UYC is a XINGLIGHT yellow SMD LED supplied in a compact 0603 surface-mount package. The package outline is 1.6 x 0.8 x 0.95 mm, with the datasheet specifying transparent/water colloid construction for the yellow luminous color.
At IF=20 mA and Ta=25°C, the LED is rated for 500 to 1200 mcd luminous intensity, 585 to 595 nm dominant wavelength, 588 nm typical peak wavelength, 1.8 to 2.4 V forward voltage, 20 nm typical half-wave width, and 35° typical viewing angle. Absolute maximum ratings include 20 mA continuous forward current, 60 mA peak forward current under the stated pulse condition, 50 mW power dissipation, and 5 V reverse voltage.
Assembly guidance includes MSL 3 handling, maximum two reflow cycles, 240±5°C for 6 s recommended maximum welding temperature, and hand-solder repair below 300°C for less than 3 s per terminal. Storage guidance specifies unopened storage within one year at <=30°C and <=60% RH, and soldering within 168 hours after opening at <=30°C and <=10% RH.

Procurement Notes
When requesting a quote for XL-TD1608UYC, 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.
