📦 Package, Dimensions & Assembly Notes
The XL-2835VRC-05 utilizes a standard 2835 footprint (2.8mm x 3.5mm x 0.8mm), making it compatible with most industry-standard pick-and-place nozzles.
- Moisture Sensitivity: The component is classified as MSL 3. 👇 It must be baked according to J-STD-033 standards if the moisture barrier bag has been opened and the floor life has been exceeded before reflow.
- Soldering Profile: It is suitable for infrared reflow soldering. For lead-free processes, the peak body temperature should not exceed 260°C (Max 6 seconds), or 255°C for 5-10 seconds depending on the specific profile used.
- Packaging: EIA standard packaging ensures compatibility with automated feeders.
🛒 Sourcing & Supply Considerations
When integrating the XL-2835VRC-05 into mass production, consider the following supply chain factors:
- Bin Consistency: Specify the required Brightness (H6/H7) and Voltage (N13) codes during ordering to maintain batch-to-batch consistency.
- Authenticity: Verify components through authorized XINGLIGHT channels to avoid counterfeits that may not meet the ROHS or reliability specs.
- Lead Time: 2835 LEDs are high-volume commodities; however, specific pinkish-red bins may have longer lead times than standard white LEDs.
- Samples: Always request pre-production samples to validate the color rendering in your specific optical assembly.
❓ FAQ
Q: What is the forward voltage range for this LED? A: The forward voltage (( V_F )) ranges from 2.8V to 3.4V when driven at the rated current of 150mA. It is available in three specific voltage bins: N13-3 (2.8-3.0V), N13-4 (3.0-3.2V), and N13-5 (3.2-3.4V).
Q: Can this LED be used with a standard lead-free reflow process? A: Yes, it is designed for SMT automation. 👇 It withstands infrared reflow soldering with a peak temperature of 255°C (Lead-free) or 260°C (Lead-based) for a maximum of 6 seconds.
Q: What does "Pinkish Red" mean in terms of wavelength? A: "Pinkish Red" is achieved by combining the red chip with a specific red colloid. The dominant wavelength (( \lambda_d )) falls between 620nm and 630nm, providing a red appearance often perceived as softer or pinkish compared to deep red.
Q: How should I handle the moisture sensitivity of this component? A: The XL-2835VRC-05 has a Moisture Sensitivity Level (MSL) of 3. If exposed to ambient air after opening the vacuum seal, you must bake it before reflow soldering to prevent internal cracking ("popcorning").
Q: What is the maximum current I can pulse this LED with? A: The maximum pulse current (( I_{FP} )) is 300mA, provided the pulse width is ≤ 0.1ms and the duty cycle is ≤ 1/10. Exceeding this may cause immediate bond wire damage.
