Product Overview
At IF=20 mA and Ta=25°C, the LED is specified for 240-600 mcd luminous intensity, 585-595 nm dominant wavelength, 590 nm typical peak wavelength, 1.9-2.4 V forward voltage, 120° typical viewing angle, and 20 nm typical half wave width. Absolute ratings include 60 mW maximum power dissipation, 30 mA maximum continuous forward current, 80 mA peak forward current under the stated pulse condition, and 5 V maximum reverse voltage.
Assembly limits include MSL 3 handling, RoHS compliance, 260°C lead soldering for no more than 6 s, and up to two reflow cycles. The datasheet also defines hand soldering limits below 30 W and below 300°C for less than 3 s per terminal, plus storage, workshop, cleaning, ultrasonic cleaning, and baking conditions for moisture control.
This part fits compact board-level indication where a yellow surface-mount LED, water-clear appearance, controlled wavelength bins, and 2012 footprint are required.

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