📌 Product Overview
💡 The XL-5050UOC is a high-brightness orange Surface Mount Device (SMD) LED from XINGLIGHT, featuring a standard 5050 footprint (5.0x5.0x1.6mm) with a water-clear colloid. 👇 It is specifically engineered for automated SMT production lines, complying with ROHS directives and EIA standard packaging requirements.
✨ Targeting indoor illumination and auxiliary lighting, this component balances luminous intensity with a wide 120° viewing angle. 🔒 Designers must prioritize the Absolute Maximum Ratings of 200mW power dissipation to ensure long-term reliability in retail and advertising module applications.
🏭 Typical Applications
Based on its high luminous intensity and warm color temperature, the XL-5050UOC is optimized for:
- 📢 Advertising Modules & Signage: High-brightness output ensures visibility in luminescent characters.
- 🏪 Retail & Counter Lighting: Suitable for jewelry display cabinets and shop lighting where color rendering is critical.
- 💡 Auxiliary & Indoor Lighting: Effective for mood lighting and supplementary illumination systems.
- 🔧 SMT Automation: Designed explicitly for infrared reflow soldering processes.

📦 Package, Dimensions & Assembly Notes
- Dimensions: The package measures 5.0 x 5.0 x 1.6mm.
- MSL Level: Rated at MSL 3 (Floor life: 168 hours). Pre-baking is required if exposed beyond this limit before reflow.
- Soldering Profile:
- Lead-Free Process: Max temp $255^\circ\text{C}$ ($+0/-5$), time above $217^\circ\text{C}$ critical.
- Lead Process: Max temp $235^\circ\text{C}$ ($+5/-0$), time above $183^\circ\text{C}$ critical.
- 🔒 Ensure strict adherence to the ramp-up rates ($\le 3^\circ\text{C}/\text{s}$) to prevent thermal shock cracking.
🚀 Sourcing & Supply Considerations
- 🏷️ Binning Codes: Utilize the specific Brightness (E5-E8), Voltage (N12-7 to N12-9), and Wavelength (HO01-HO03) codes for consistent lot-to-lot uniformity.
- ⚙️ SMT Compatibility: Verify that your pick-and-place equipment is tuned for EIA standard packaging to minimize drop-out rates.
- ✅ Authenticity: Source through authorized channels to guarantee ROHS compliance and avoid counterfeit components with varied thermal performance.
❓ Frequently Asked Questions (FAQ)
Q: What is the critical storage requirement for this LED before assembly?
A: The XL-5050UOC has a Moisture Sensitivity Level (MSL) of 3. If the sealed bag is open and the components are not mounted within 168 hours (1 week), they must be baked at specific temperatures to drive out moisture and prevent "popcorning" during reflow soldering.
Q: Can I drive this LED at its peak current continuously?
A: No. The Absolute Maximum Rating for Peak Forward Current ($I_{FP}$) is 120mA, but this is strictly for pulsed operation with a pulse width $\le 0.1\text{ms}$ and a duty cycle $\le 1/10$. For continuous operation, the current must not exceed 60mA to avoid thermal runaway.
Q: How does the viewing angle affect my light output design?
A: This LED features a wide 120° viewing angle. While this provides excellent diffusion for area lighting (like advertising modules), it reduces the intensity per unit area compared to a narrow-beam LED. Designers should account for this wider spread when calculating total luminous flux requirements.
Q: What is the maximum tolerance for Forward Voltage?
A: Under standard test conditions ($60\text{mA}$), the Forward Voltage ($V_F$) can range from 1.8V to 2.4V. When designing arrays or drivers, you must plan for the 2.4V maximum to ensure consistent current regulation across all bins.
Q: Is this component suitable for high-vibration environments?
A: While the datasheet specifies suitability for infrared reflow soldering (common in automotive/industrial PCBs), it does not explicitly list AEC-Q101 or Vibration Test results in the provided summary. For high-vibration applications, verify mechanical shock resistance or secure the encapsulation with potting compounds.
