📦 Package, Dimensions & Assembly Notes
The XL-B504RGBCRGB features a standard 5mm ($F5$) radial package with specific appearance dimensions of $5.8 \times 5.0 \times 8.7 \times 28mm$.
- Moisture Sensitivity: Classified as MSL Level 2. Components must be baked according to J-STD-033 if exposed to ambient moisture beyond the floor life before soldering.
- Assembly: Designed for wave soldering (max 240°C) and manual welding (max 300°C for 3s). 📈 The lead spacing and length are optimized for standard PCB lead pitches.
- Packaging: EIA standard compliant packaging ensures compatibility with automated insertion equipment.
🚀 Sourcing & Supply Considerations
For OEMs integrating the XL-B504RGBCRGB, consider the following supply chain factors:
- Bin Consistency: When scaling to mass production, specify the Brightness (A7-B8) and Voltage (N12/N13) bins to maintain uniformity in brightness and power consumption across your BOM.
- Authenticity Verification: Source from authorized distributors to avoid counterfeits that may not meet the ROHS compliance or 2000V ESD protection ratings.
- Sample Evaluation: Request pre-production samples with specific bin codes to validate color mixing and diffuser performance in your specific optical assembly.
❓ Frequently Asked Questions
Q: What is the forward voltage requirement for the Green and Blue chips?
A: Both Green and Blue chips have a typical forward voltage range of 2.8V to 3.4V at 20mA. This is higher than the Red chip (1.8V - 2.4V), so your driver circuit must be capable of supplying the higher voltage or use separate resistors for each channel to balance current.
Q: Can this LED be used in high-humidity environments?
A: Yes, the datasheet confirms it passes high-humidity endurance tests ($85^\circ C$, 85-90% RH). However, it is rated at MSL 2, meaning it can withstand floor life of up to 1 year at $<30^\circ C$ / 60% RH before baking is required for soldering.
Q: What is the peak current capability?
A: The Absolute Maximum Rating for peak forward current ($I_{FP}$) is 80mA. However, this is intended for pulsed operation. For continuous operation, stay within the 20mA limit to avoid thermal rollover and reduce lifespan.
Q: How should I handle the soldering process to avoid damage?
A: Ensure the soldering point is at least 2.0mm from the bottom of the epoxy colloid. Do not exceed 240°C for wave soldering (max 6 seconds) or 300°C for manual welding (max 3 seconds). 🔒 Adhering to these limits prevents degradation of the internal wire bonds.
Q: Are there specific wavelength bins available?
A: Yes, XINGLIGHT provides tight wavelength binning. For example, Red is binned between HR02 (620-625nm) and HR03 (625-630nm). Specify these codes if your application requires strict color coordination across multiple LEDs.
