- Sample Testing: Always evaluate samples from the specific batch to verify color temperature consistency before mass production.
❓ FAQ
Q: What is the maximum drive current for continuous operation? A: The Absolute Maximum Rating for continuous Forward Current (IF) is 350 mA. Exceeding this current without adequate heat sinking will likely degrade the LED lifespan or cause immediate failure.
Q: Can this LED be used for high-density PCB arrays? A: Yes, the 2.5x2.5mm footprint is designed for compact arrays. However, designers must calculate the total Power Dissipation (PD) to ensure the PCB copper plating can handle the thermal load, keeping the Junction Temperature (Tj) below 145°C.
Q: What precautions should be taken during soldering? A: The device supports Reflow Soldering with a peak temperature of 260°C for a maximum of 6 seconds. As a Moisture Sensitivity Level (MSL) 3 component, it must be baked according to J-STD-033 guidelines if the dry pack has been opened for more than 168 hours to prevent "popcorning" damage.
Q: How do I interpret the Color Temperature codes? A: The datasheet provides codes like UW7-10 (5500-6000K) through UW13-10 (7000-7500K). You must specify the required bin code when purchasing to ensure the white light matches your design requirements, as this range covers cool white to daylight shades.
Q: Is the HD2525UWC-A2 ROHS compliant? A: Yes, the datasheet explicitly states that this is an environmental protection product that meets ROHS requirements, making it suitable for markets with strict hazardous substance restrictions.
