Product Overview
XL-2012UYC-FJ is a XINGLIGHT yellow SMD indicator LED supplied in a compact 2012 package with 2.0 x 1.2 x 0.8 mm outline dimensions. The device uses a transparent water-clear colloid and is specified as a yellow luminous-color LED for indicator use in space-constrained assemblies.
At IF=20 mA and Ta=25°C, the LED is rated for 240 to 600 mcd luminous intensity, 585 to 595 nm dominant wavelength, 590 nm typical peak wavelength, 1.9 to 2.4 V forward voltage, and 120° typical viewing angle. The half-wave width is 20 nm typical, and reverse current is specified at no more than 1 µA at VR=5 V.
Absolute maximum ratings at Ta=25°C include 60 mW power dissipation, 30 mA continuous forward current, 80 mA peak forward current under pulsed conditions, and 5 V reverse voltage. Assembly guidance includes reflow soldering up to two times, recommended maximum welding temperature of 240 ±5°C for 6 s, and MSL 3 handling with defined storage and baking conditions.

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.
