📌 Package, Dimensions & Assembly Notes
The XL-302UYD utilizes a compact F3 package with dimensions of 3.8x3.0x5.2mm (LxWxH). For reliable SMT assembly, the soldering point must be at least 2.0mm away from the bottom of the LED's colloid to prevent heat damage. Manual soldering should be performed at 300°C for a maximum of 3 seconds. The device is supplied in moisture-proof, anti-static EIA standard packaging with a Moisture Sensitivity Level (MSL) of 2.
📌 Sourcing & Supply Considerations
- Binning: The XL-302UYD is available in specific brightness (A2-A6), voltage (N12-7 to N12-9), and wavelength (HY03-HY06) grades for consistent performance.
- Reliability: Components have passed extensive reliability tests, including 1000-hour life testing and thermal cycling.
- Compliance: The product is RoHS compliant and suitable for a wide range of general electronics applications.
- Verification: For high-reliability applications (e.g., automotive, medical), direct consultation with XINGLIGHT is required to access specific qualification data.
