📏 Package, Dimensions & Assembly Notes
The XL-304UYC is packaged in F3 format with a lead length of 28mm. Key dimensions are 3.8mm (D) x 3.0mm (H). For reliable assembly, the soldering point must be kept at least 2.0mm away from the bottom of the LED's epoxy body to prevent heat damage. It is supplied in moisture-proof, anti-static EIA standard packaging, with a Moisture Sensitivity Level (MSL) of 2.
🚀 Sourcing & Supply Considerations
- Parameter Binning: Available in brightness (A2-A6), voltage (N12-7 to N12-9), and wavelength (HY03-HY06) grades for precise application matching.
- Quality Assurance: RoHS compliant and backed by extensive reliability testing data for high-stress environments.
- Supply Chain: Verify sourcing through authorized distributors to ensure component authenticity and avoid counterfeit parts.
❓ FAQ
Q: What is the MSL (Moisture Sensitivity Level) for the XL-304UYC, and what does it mean for my production process? A: The MSL is 2. This means the components must be stored in dry conditions and typically baked before reflow soldering if exposed to ambient humidity for an extended period, as per standard industry practices for level 2 devices.
Q: Can the XL-304UYC be used in high-reliability applications like medical or automotive systems? A: While the LED has passed reliability testing for general use, for applications with stringent requirements like AEC-Q102 (automotive) or medical certifications, you must consult with XINGLIGHT for specific data and suitability confirmation.
Q: What is the difference between the typical and maximum forward voltage (VF)? A: The typical VF is 2.2V under standard test conditions (IF=20mA, Ta=25°C). The maximum VF is 2.4V, representing the upper limit of performance variation across the production batch. This is critical for designing stable driver circuits.
Q: How is the luminous intensity graded, and can I specify a certain brightness range? A: Yes, the XL-304UYC is graded into bins (e.g., A4: 400-500 mcd). You can specify the required brightness bin when placing an order to ensure consistency across your product's indicators.
