Product Overview
XL-3433UYC-05 is a XINGLIGHT yellow SMD LED supplied in a 3433 surface-mount package. The outline dimensions are 3.4 x 3.3 x 1.9 mm, and the luminous color is yellow with a colorless transparent colloid. The component is classified as MSL 3 for moisture sensitivity handling.
Electrical ratings at Ta=25°C include 500 mW maximum power dissipation, 150 mA maximum continuous forward current, 300 mA peak forward current under pulse width <=0.1 ms and duty <=1/10, 5 V maximum reverse voltage, and 2000 V ESD rating. The operating and storage temperature ranges are both -40 to +85°C.
At IF=150 mA and Ta=25°C, the device specifies 20 min to 33 max LM luminous flux, 585 to 595 nm dominant wavelength, 590 nm typical peak wavelength, 1.8 to 2.4 V forward voltage, 120° typical viewing angle, 20 nm typical half wave width, and reverse current <=5 µA at VR=5 V.
Assembly guidance includes 260°C <=6 s lead soldering, two reflow cycles maximum, 240±5°C for 6 s recommended maximum welding temperature, and defined storage, baking, and cleaning conditions for post-soldering process control.

Procurement Notes
When requesting a quote for XL-3433UYC-05, 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.
