Product Overview
The XL-0401UBC is a XINGLIGHT high brightness blue SMD LED supplied in a compact 0401 package. Its appearance dimensions are 1.05 x 0.35 x 0.4 mm, with blue luminous color and transparent colloid construction documented in the manufacturer technical datasheet.
At IF=20 mA and Ta=25°C, the LED is specified for 120 to 240 mcd luminous intensity, 460 to 475 nm dominant wavelength, 465 nm typical peak wavelength, 25 nm typical half wave width, and 120° typical viewing angle. Forward voltage is specified from 2.6 to 3.4 V, with reverse current limited to <=1 µA at VR=5 V.
Absolute maximum ratings include 70 mW power dissipation, 20 mA continuous forward current, 80 mA peak forward current under the stated pulse condition, 5 V reverse voltage, 2000 V ESD rating, and -40 to +85°C operating and storage temperature ranges. Assembly guidance includes MSL 3 handling, maximum two reflow cycles, opened package floor life of 168 hours at <=30°C and <40%RH, and defined baking conditions after moisture exposure or exceeded storage time.

Procurement Notes
When requesting a quote for XL-0401UBC, 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.
