📦 Package, Dimensions & Assembly Notes
The component utilizes an industry-standard EIA-compliant package with moisture-proof and anti-electrostatic foil bag packaging (MSL 2). 🔒 Key physical and assembly specifications are detailed below:
- Dimensions: 10.0mm (L) x 9.0mm (W) x 4.5mm (H) with a tolerance of ±0.25mm unless noted.
- Soldering: Manual or Wave Soldering is not recommended due to plastic package limitations. 🔥 Use IR Reflow with a peak temperature of 260℃ for ≤6 seconds.
- Mechanical Integrity: Leads withstand 2.5N load (0°~ 90° bend). Ensure PCB layout accounts for the 4.5mm height to avoid mechanical interference in enclosures.
- Shelf Life: Proper storage in the provided moisture-proof bags is critical to maintain MSL 2 compliance and prevent thermal degradation during reflow.
📈 Sourcing & Supply Considerations
For procurement teams and supply chain managers, verifying the consistency of optical bins is crucial for visual uniformity in mass production. 🚨 XINGLIGHT offers specific grading for brightness (A1-A7), voltage (N12/N13), and wavelength (HR/HYG codes) to match strict BOM requirements.
When sourcing the XL-DZ304SURSYYG, confirm the required bin codes with your distributor to ensure color consistency across batches. 🤝 Verify authenticity by requesting full traceability documentation and ensure stock is rotated to respect the component's long operating life specifications.
❓ Frequently Asked Questions
Q: What is the forward voltage requirement for the Yellow-Green chip?
A: The Yellow-Green (YG) chip typically requires a forward voltage (VF) between 1.8V and 2.6V at 20mA. Designers should select the appropriate bin code (e.g., N12-7 vs N13-1) to match the driver circuit's voltage headroom.
Q: Can this LED be used in high-temperature automotive environments?
A: While the operating range extends to +85℃, this model is not explicitly classified as Automotive Grade (AEC-Q102) in the provided sheet. It is optimized for industrial IoT and medical devices within the -40℃ to +85℃ range.
Q: What does MSL Level 2 mean for my assembly line?
A: Moisture Sensitivity Level 2 means the components can be exposed to the ambient environment (≤30°C/60%RH) for up to one year before soldering. After opening the moisture-proof bag, if not used within 168 hours (7 days), baking may be required prior to reflow.
Q: How is the brightness graded for bulk orders?
A: Brightness is binned based on Luminous Intensity (Iv). Codes range from A1 (50-100 mcd) to A7 (700-900 mcd). For uniform panel lighting, ensure all units in a single BOM batch share the same brightness code.
Q: Is the Red/Green light independently controllable?
A: The datasheet refers to "RedGreen" colloids and lists separate electrical parameters (R/YG) for current and power dissipation, implying a multi-die structure. However, confirm the pin-out configuration (Common Anode vs. Common Cathode) with the mechanical drawing before PCB layout.
