Product Overview
XL-3216UYC is a XINGLIGHT yellow SMD LED supplied in a 3216 surface-mount package. The package outline is 3.2 x 1.6 x 0.8 mm with a transparent/water clear colloid, supporting compact indicator and display-lighting placements where a yellow emission color is required.
At IF=20 mA and Ta=25°C, the LED is specified for 80 to 240 mcd luminous intensity, 585 to 595 nm dominant wavelength, 590 nm typical peak wavelength, 20 nm typical half wave width, and 120° typical viewing angle. Forward voltage is specified from 1.8 to 2.4 V, with reverse current limited to <=1 µA at VR=5 V.
Absolute maximum ratings include 50 mW power dissipation, 20 mA continuous forward current, 80 mA peak forward current under the stated pulse condition, 5 V reverse voltage, and -40 to +85°C operating and storage temperature ranges. Assembly guidance covers lead soldering at 260°C for <=6 s, a recommended maximum welding temperature of 240±5°C for 6 s, up to two reflow cycles, and MSL 3 moisture handling.

Procurement Notes
When requesting a quote for XL-3216UYC, 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.
