Procurement Notes
When requesting a quote for XL-1608UBC-06FB, 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.
FAQ
What package size does XL-1608UBC-06FB use?
XL-1608UBC-06FB uses a 0603 SMD package with outline dimensions of 1.6 x 0.8 x 0.6 mm. The datasheet lists a general dimension tolerance of ±0.25 mm unless otherwise noted.
What are the main optical ratings at 20 mA?
At IF=20 mA and Ta=25°C, the LED is specified for 125 to 240 mcd luminous intensity, 460 to 475 nm dominant wavelength, 460 nm typical peak wavelength, 25 nm typical half wave width, and 120° typical viewing angle.
What electrical limits apply to this blue SMD LED?
Absolute maximum ratings at Ta=25°C include 70 mW power dissipation, 20 mA continuous forward current, 80 mA peak forward current under the stated pulse condition, 5 V reverse voltage, and a 2000 V ESD rating.
What soldering limits are stated for assembly?
The datasheet states 260°C for no more than 6 seconds for lead soldering, a maximum of two reflow cycles, and a recommended maximum welding temperature of 240±5°C for 6 seconds. Hand soldering is limited to <300°C for under 3 seconds per terminal.
How should opened packages be stored before soldering?
After opening, the LED should be stored at ≤30°C and ≤40% RH and soldered within 168 hours, or 7 days. If storage time is exceeded or the moisture absorbent has faded, the listed baking condition is 60±5°C for 24 hours.
