📌 Product Overview
The XINGLIGHT XL-3020UYC is a high-performance surface-mount device (SMD) LED designed for automated assembly. 💡 It features a compact 3.0 x 2.0 x 1.3mm package with a transparent water-clear colloid, emitting a dominant yellow wavelength (585–595nm).
Targeting indoor and commercial lighting, this component is ideal for fluorescent tubes, light strips, and LCD backlights. The real design focus lies in its robust EIA-standard packaging, which supports infrared reflow soldering processes while maintaining strict compliance with ROHS environmental directives.
🔦 Typical Applications
Based on its optical characteristics and 120° viewing angle, the XL-3020UYC is suited for:
- Commercial Lighting: 👇 Advertising characters, light boxes, and signage requiring consistent yellow luminosity.
- Indoor Illumination: Flexible light strips and downlights where space is constrained.
- Backlighting: LCD indicator lights and switch backlighting.
- Decorative Lighting: Accent lighting in consumer electronics and appliances.

- Soldering Compatibility: Suitable for infrared reflow and automated SMT production.
- Lead-Free Process: Peak temp 255°C (Max 6s above 217°C).
- With Lead Process: Peak temp 235°C (Max 10s above 183°C).
- Packaging: Supplied in EIA standard tape and reel formats for high-volume pick-and-place efficiency.
🚀 Sourcing & Supply Considerations
- Supply Chain: Verify authenticity through authorized XINGLIGHT distributors to avoid counterfeit components.
- Bin Consistency: For mass production, specify brightness (D9-E3) and voltage (N12-7 to N12-9) bins to ensure uniformity across light strips.
- Sample Support: Request pre-production samples with specific grading codes to validate color temperature and intensity in your actual housing design.
- Technical Exchange: Consult with LDeepAI for cross-referencing or reliability testing data beyond the standard datasheet.
❓ FAQ
Q: What is the MSL level of the XL-3020UYC and why does it matter?A: The XL-3020UYC has a Moisture Sensitivity Level (MSL) of 3. This means it can be exposed to ambient factory conditions (≤30°C/60%RH) for 168 hours (one week) before baking is required prior to reflow soldering to prevent internal cracking ("popcorning").
Q: Can this LED be used in outdoor lighting fixtures?A: While the operating temperature range is -40°C to +85°C, the transparent colloid is designed for indoor use. For outdoor applications, additional protection (encapsulation or IP-rated housing) is required to shield the SMD from direct UV exposure and water ingress.
Q: What is the difference between Dominant Wavelength and Peak Wavelength?A:Dominant Wavelength (λd) (585-595nm) defines the perceived color of the light as seen by the human eye. Peak Wavelength (λp) (590nm Typ) is the specific wavelength at which the light intensity is physically maximum on the spectral curve.
Q: What are the soldering profile limits for lead-free assembly?A: For lead-free processes, the peak body temperature must not exceed 255°C. The time above 217°C (liquidous) should be strictly controlled between 60 to 120 seconds to prevent thermal damage to the epoxy or wire bonds.
Q: How should I handle the bin codes (e.g., HY03, E1) when ordering?A: Bin codes sort the LEDs by specific wavelength (HY03-HY06) and brightness (D9-E3). To ensure a visually uniform appearance in your final product, you should order a single bin code rather than mixed batches.
Q: What is the maximum current I can pulse this LED at?A: The Peak Forward Current (IFP) is rated for 80 mA. However, this applies only to pulses with a width ≤ 0.1ms and a duty cycle ≤ 1/10. Continuous operation must not exceed 20 mA.
