Product Overview
Electrical and optical ratings are defined at Ta=25°C unless otherwise stated. At IF=20 mA, the LED provides 150 to 300 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 graded from 2.6 to 3.4 V, with reverse current rated at <=1 µA at VR=5 V.
Absolute maximum ratings include 100 mW power dissipation, 30 mA continuous forward current, 80 mA peak forward current under the specified pulse condition, and 5 V maximum reverse voltage. Operating and storage temperature ranges are both -40 to +85°C.
Assembly guidance includes 260°C for <=6 s lead soldering, up to two reflow cycles, and a recommended maximum welding temperature of 240±5°C for 6 s. The part fits compact blue indicator, surface-mount signaling, and wavelength-binned blue LED applications.

Procurement Notes
When requesting a quote for XL-2012UBC-A, 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.
