WS-C4040YGC-4J-1T 4040 Side View Yellow-Green SMD LED
Model WS-C4040YGC-4J-1T is a 4040 side-view yellow-green SMD LED with dimensions 4.0×4.0×3.55mm and rated power of 0.04W. It features an InGaN chip with transparent epoxy encapsulation, driven at standard 20mA. With dominant wavelength range of 570-575nm, luminous intensity of 60-120mcd, and forward voltage of 1.8-2.2V, this LED is rated MSL Level 5a and compatible with full SMT assembly and lead-free reflow soldering. Offering 2000V HBM ESD resistance and operating temperature from -40℃ to +85℃, it complies with RoHS and REACH standards. Ideal for automotive interior backlighting, instrument indicators, home appliances, industrial control panels, and light guide side backlighting applications.
Core Features
Standard 4.0×4.0mm side-emitting outline with 3.55mm height
120° wide viewing angle for even lateral light output
Low 0.04W power consumption with stable yellow-green spectrum (570-575nm)
Luminous intensity from 60 to 120mcd
MSL Level 5a for outstanding moisture resistance
Clear epoxy package with excellent thermal and aging resistance
2000V HBM ESD protection against electrostatic damage
Compliant with international RoHS & REACH environmental requirements
Failure Standard: VF＞1.1×USL, IR＞10μA, Iv＜0.7×LSL are defined as defective.
Reflow Soldering Requirements
Only single reflow soldering is permitted; repeated reflow is prohibited.
Leaded solder: Peak ≤230℃, max heating rate 4℃/s, soak time over 120s at 140-160℃.
Lead-free solder: Peak ≤260℃, max heating rate 4℃/s, soak time over 120s at 180-200℃.
Packing Specification
Packed by tape & reel, 1503 pieces per reel. Cover tape peeling force: 0.1-0.7N under 10° peeling angle. Sealed with aluminum moisture-proof bag equipped with desiccant.
Storage & Operation Guidance
Unopened reels: Store at 0-30℃, RH＜60% in moisture-proof cabinet for maximum 60 days; perform first article inspection before production.
Opened reels: Finish all unpacked LEDs within 24 hours; bake residual LEDs at 60℃ for 12-24 hours before reuse. Never mix LEDs from different batches.
Assembly: Complete reflow process right after SMT mounting with full ESD protection.
Outdoor applications: Apply secondary lens plus potting glue instead of direct surface encapsulation; select low oxygen permeability adhesive.
