📏 Package, Dimensions & Assembly Notes
The XL-304UBD uses a moisture-proof, anti-static foil bag (EIA standard). Key dimensions: 3.8x3.0x5.2mm (body) with 28mm leads. Soldering must keep the joint ≥2.0mm from the epoxy body to avoid damage. MSL rating is 2, requiring standard baking if exposed to humidity. Lead bending tests (2.5N, 0°-90°) confirm mechanical integrity.
🚀 Sourcing & Supply Considerations
- Binning Codes: Brightness (A4-A7), voltage (N13-3 to N13-5), and wavelength (HB04-HB06) ensure consistency.
- Authenticity: Verify packaging and traceability with authorized distributors.
- Lead Times: Confirm stock for mass production; long-term storage requires dry conditions.
❓ FAQ
Q: What is the brightness grading for the XL-304UBD?
A: Brightness is binned into A4 (300-400mcd), A5 (400-500mcd), A6 (500-700mcd), and A7 (700-900mcd) at IF=20mA.
Q: Is this LED suitable for automotive applications?
A: Yes, but verify specific requirements like temperature cycling (-40°C to +85°C) and vibration resistance.
Q: What are the soldering restrictions?
A: Reflow soldering ≤240°C for ≤6s; manual soldering ≤300°C for 3s. Keep joints ≥2.0mm from the body.
Q: How should I store unused LEDs?
A: Store in original packaging at ≤30°C and ≤70% RH. For long-term storage, use a dry environment.
Q: Can this LED replace a similar blue LED in existing designs?
A: Cross-check electrical specs (VF, Iv), dimensions, and thermal limits. Ensure the binning codes match your requirements.
Q: What is the reliability testing data?
A: Passes 1000hrs of working life, high-temp/humidity (85°C/90% RH), and 100 cycles of thermal shock (-45°C to 105°C).
