📌 Product Overview
The XL-5050YWC is a 5.0 x 5.0 x 1.6 mm surface-mount device (SMD) from XINGLIGHT, categorized within the 5050 LED family. It utilizes a yellow colloid to emit high-brightness monochromatic light, specifically designed for applications requiring warm accent lighting within the 1600K to 2200K color temperature range.
💡 This component is engineered for automated assembly processes. It is fully compliant with RoHS directives and suitable for standard SMT production lines. Engineers utilizing this device must prioritize thermal management calculations, as the power dissipation reaches 200 mW, which impacts PCB copper weight requirements.
🚀 Typical Applications
Based on its optical characteristics (1600K-2200K CCT) and 120-degree viewing angle, the XL-5050YWC is optimized for directional ambient lighting rather than general illumination.
- Indoor & Auxiliary Lighting: Providing warm accent lighting in residential or commercial settings.
- Signage & Advertising: Ideal for luminescent characters and advertising modules where specific yellow wavelengths are required.
- Retail Display: Effective for jewelry display counters and shop lighting, enhancing the visual appeal of merchandise.
- Accent & Decor: Used in cabinet lighting and specialty decorative fixtures.

🛒 Sourcing & Supply Considerations
When integrating the XL-5050YWC into BOMs, procurement teams should verify the specific binning codes (Brightness and Voltage) required to maintain color consistency across batches.
- Supply Chain Risk: Ensure suppliers are authorized XINGLIGHT distributors to avoid counterfeits, particularly given the prevalence of fake LEDs in the open market.
- Sample Evaluation: Request specific bin samples (e.g., Voltage N13-4) to validate driver circuit compatibility before volume ordering.
- Lead Time: Verify current stock levels for the specific "Yellow Colloid" variant, as high-brightness variants often have longer lead times than standard white LEDs.
❓ FAQ
Q: What is the MSL level of the XL-5050YWC, and what does it mean for my assembly line?
A: The XL-5050YWC has a Moisture Sensitivity Level (MSL) of 3. This means the components can be exposed to ambient factory conditions for 168 hours (one week) before they must be reflowed. If stored longer or opened beyond this time, they require baking (per J-STD-033) to remove moisture and prevent internal cracking during soldering.
Q: Can the XL-5050YWC be driven at a higher current for short bursts?
A: Yes, the datasheet specifies a Peak Forward Current (IFP) of 120 mA. However, this is strictly limited to pulses with a width ≤0.1ms and a duty cycle ≤1/10. Continuous operation must not exceed the Max Continuous Forward Current of 60 mA.
Q: What is the difference between the various Voltage Grading codes (N13-3, N13-4, N13-5)?
A: These codes indicate the forward voltage (Vf) range of the LED at 60mA.
- N13-3: 2.8V - 3.0V
- N13-4: 3.0V - 3.2V
- N13-5: 3.2V - 3.4V
Selecting a single bin helps ensure uniform brightness and simplifies the design of the LED driver circuit.
Q: Is this component suitable for outdoor use?
A: While the operating temperature range is wide (-40°C to +85°C), the datasheet lists "Indoor lighting" applications and the packaging is not explicitly rated for IP67 water ingress. For outdoor use, additional protective encapsulation or housing is required to shield the SMD component from direct moisture and UV exposure.
Q: How do I verify the authenticity of XINGLIGHT components?
A: Authenticity can be verified by purchasing from authorized distributors and checking the packaging for correct EIA standard labeling and Lot/Date codes. Cross-referencing the brightness grading code (H8-J2) with measured lumen output upon receipt is also a standard quality control practice.
