👇 Critical Design Tip: Exceeding the junction temperature or the 20mA continuous current limit will significantly degrade the lifespan and luminous output of the LED.
🏗️ Package, Dimensions & Assembly Notes
The XL-3020UGC utilizes a standard 3020 package form factor, optimized for automated pick-and-place machines.
- Dimensions: The outline measures 3.0mm (L) x 2.0mm (W) x 1.3mm (H).
- Moisture Sensitivity: The MSL is rated at Level 3. 👉 Ensure proper baking and handling if the components have been exposed to ambient humidity for extended periods prior to reflow.
- Soldering Compatibility: Suitable for both Lead (Tmax 235°C) and Lead-Free (Tmax 255°C) infrared reflow processes.
- Assembly: Designed for SMT automatic production. Follow the recommended reflow profile: preheat temperature max 3°C/s, and time above 217°C (lead-free) between 60-120 seconds.
📦 Sourcing & Supply Considerations
When integrating the XL-3020UGC into your bill of materials, keep these supply chain factors in mind:
- Packaging: Components are supplied in EIA standard compliant packaging, facilitating seamless integration into existing SMT feeders.
- Bin Selection: Specify brightness (F2-F5) and voltage (N13) codes during procurement to match your specific driver circuit and brightness requirements.
- Sample Availability: Request samples for color temperature and intensity verification before committing to mass production orders.
- Authenticity: Always source through authorized channels to guarantee ROHS compliance and avoid performance variability caused by counterfeit components.
❓ FAQ
Q: What is the MSL level of the XL-3020UGC, and why does it matter? A: The Moisture Sensitivity Level is 3. This means the components can withstand floor life of up to 168 hours (one week) in a factory environment (<30°C/60% RH) before baking is required. 👉 If floor life is exceeded, the components must be baked at 125°C for a prescribed time to prevent internal cracking ("popcorning") during reflow soldering.
Q: Can this LED be used in outdoor lighting fixtures? A: While the storage and operating temperatures range from -40°C to +85°C, the XL-3020UGC is primarily designed for indoor applications. For outdoor use, it must be housed in an IP-rated fixture with adequate waterproofing, as the water-clear colloid itself is not rated for direct UV or water exposure.
Q: What is the difference between Dominant Wavelength and Peak Wavelength? A: The Peak Wavelength (525nm Typ) is the physical point of maximum spectral emission. The Dominant Wavelength (515-530nm) describes the perceived color of the light by the human eye. For the XL-3020UGC, the dominant wavelength falls within the emerald green spectrum.
Q: What are the specific requirements for Lead-Free reflow soldering? A: For a Lead-Free process, the peak temperature should not exceed 255°C. The time above 217°C should be strictly controlled between 60 to 120 seconds. The ramp-up rate should not exceed 3°C/second to prevent thermal shock to the LED die.
Q: How should I handle the brightness grading codes? A: The XL-3020UGC is graded from F2 to F5 (1150-1800 mcd). If your design requires uniform brightness across a panel, you must specify a single bin code (e.g., only F4). Mixing bins will result in visible patches of different light intensities on the finished product.
