📌 Product Overview
The XINGLIGHT XL-2835WWC-02 is a high-performance 2835 package SMD LED designed for reliable warm white illumination. 💡 With a compact 2.8x3.5mm footprint, it balances luminous intensity up to 33 Lumens with energy efficiency, making it ideal for modern lighting fixtures.
Target applications include indoor and commercial lighting, such as downlights and light strips, where consistent color temperature is critical. 👇 Real design focus should be placed on thermal management to maintain the 2800K-3200K color stability and ensure the 60mA drive current does not exceed the component's thermal dissipation capacity.
🚀 Typical Applications
Based on the datasheet parameters and optical characteristics, the XL-2835WWC-02 is best suited for applications requiring warm white tones and high reliability.
- Indoor Lighting: 💡 Optimized for fluorescent tubes, residential light strips, and recessed downlights requiring CRI Ra>70.
- Commercial Display: 👇 Ideal for advertising light boxes and illuminated signage where uniform 120-degree viewing angle is beneficial.
- Backlighting: Suitable for LCD backlight units in consumer electronics or indicator panels.
- Decorative Lighting: ✨ Flexible strip lighting for accent or ambient lighting in hospitality and retail environments.

- Lead Process: Peak max 235°C (Time above 183°C: 60-150s).
🛒 Sourcing & Supply Considerations
To ensure production consistency and supply chain security, consider the following factors when procuring the XL-2835WWC-02.
- Bin Selection: 💡 Specify exact bins for Voltage (N13-3 to N13-5) and Brightness (J1-J3) to ensure lot-to-lot consistency.
- Packaging: 📦 Verify the tape is EIA standard packaging to match your pick-and-place feeders.
- Compliance: ✨ Ensure the batch carries valid ROHS certification for environmental compliance.
- Authenticity: 👇 Source directly from XINGLIGHT or authorized channels to guarantee the 2000V ESD rating and reliability specs.
❓ Frequently Asked Questions (FAQ)
Q: What is the recommended drive current for optimal lifespan? A: While the absolute maximum is 60mA, driving the LED at 50-55mA is often recommended to balance high luminosity (up to 33LM) with long-term thermal management and reliability.
Q: Can this LED be used in outdoor lighting fixtures? A: The datasheet specifies storage and operating temperatures up to +85°C. While suitable for enclosed outdoor fixtures, the IP rating depends entirely on your housing design, as the LED component itself is not waterproof.
Q: What does the "MSL 3" rating mean for my production line? A: MSL 3 (Moisture Sensitivity Level) means the components must be soldered within 168 hours (1 week) of opening the vacuum-sealed bag. If exposed longer, you must bake them at 125°C for 24 hours to prevent popcorning damage during reflow.
Q: Are there specific grading codes for color temperature? A: Yes. The datasheet lists codes like WW2-4 (2800-3000K) and WW4-4 (3000-3200K). 👇 Always specify the required code to your supplier to ensure the warmth of the white light matches your design intent.
Q: Is this component compatible with lead-free soldering processes? A: Yes. The datasheet provides a specific profile for lead-free processes, allowing a peak temperature of 255°C. 💡 Ensure your reflow oven profile does not exceed this limit or the 5-10 second soak time at peak temperature.
