📦 Package, Dimensions & Assembly Notes
The XL-0401SURC is supplied in EIA standard tape-and-reel packaging, compatible with automatic mounters. Its ultra-compact 0401 package (1.05x0.35x0.5mm) requires precise SMT placement. It is suitable for both leaded and lead-free reflow soldering processes. Moisture Sensitivity Level (MSL) is 3, necessitating standard dry storage and baking procedures before assembly to prevent popcorning during reflow.
🚀 Sourcing & Supply Considerations
- Ensure procurement from authorized XINGLIGHT distributors to guarantee authenticity and traceability.
- Utilize the provided binning codes (D1-D4 for brightness, M17-9 to M18-5 for voltage, HR01-HR03 for wavelength) for precise BOM management.
- Verify packaging specifications (EIA standard) and MSL level with your supplier to align with factory handling protocols.
❓ FAQ
Q: What is the Moisture Sensitivity Level (MSL) for the XL-0401SURC? A: The MSL is 3. This component requires standard dry storage conditions and may need to be baked according to IPC/JEDEC standards if exposed to ambient conditions for an extended period before reflow soldering.
Q: What are the available brightness bins for the XL-0401SURC? A: The LED is graded into four brightness bins: D1 (50-80 mcd), D2 (80-120 mcd), D3 (120-150 mcd), and D4 (150-180 mcd), all measured at IF=20mA.
Q: Is the XL-0401SURC suitable for lead-free reflow soldering? A: Yes, it is suitable for both leaded and lead-free (Pb-free) infrared reflow soldering processes. The peak temperature must not exceed 235°C for leaded profiles or 260°C for lead-free profiles, with specific time-at-temperature limits as defined in J-STD-020C.
Q: How does the wavelength binning work for this LED? A: The dominant wavelength is graded into three bins: HR01 (615-620 nm), HR02 (620-625 nm), and HR03 (625-630 nm), measured at IF=20mA. This allows for color consistency in specific applications.
Q: What is the recommended forward current for standard operation? A: The recommended maximum continuous forward current is 20 mA. A peak forward current of 60 mA can be used for very short pulses (≤0.1ms, duty cycle ≤1/10) for brief, high-intensity illumination.
