Product Overview
Electrical and optical characteristics are specified at IF=20 mA and Ta=25°C unless otherwise stated. Key values include 400 to 900 mcd luminous intensity, 7500 to 15000 K color temperature, typical chromaticity coordinates of X=0.29 and Y=0.30, 2.6 to 3.4 V forward voltage, 1 μA maximum reverse current at VR=5 V, and a 120° typical viewing angle. Absolute maximum ratings include 70 mW power dissipation, 20 mA continuous forward current, 80 mA peak forward current, and 5 V maximum reverse voltage.
Assembly guidance includes 260°C for up to 6 s as a lead soldering limit, a recommended maximum welding temperature of 240±5°C for 6 s, and no more than two reflow cycles. Hand soldering is specified with an iron below 30 W, below 300°C, and below 3 s per terminal. These parameters support use in compact PCB-mounted white indicator, backlight, and signal-light applications.

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