❓ FAQ
Q: What is the maximum drive current for the XL-3570? A: The Absolute Maximum Forward Current rating is 2000mA. While pulse currents can reach higher peaks (3000A), continuous operation should not exceed 2000mA to prevent thermal runaway.
Q: What is the thermal resistance of this LED? A: The thermal resistance from junction to solder point (Rth-j-s) is typically between 3°C/W and 5°C/W. This low resistance is crucial for maintaining junction temperatures below the 145°C limit.
Q: Can this component be used for automotive exterior lighting? A: Yes, the XL-3570 is specifically listed for automotive lighting applications. It supports a wide operating temperature range (-40°C to +135°C) and utilizes Flip Chip technology for robustness.
Q: What are the soldering profile requirements? A: The LED supports standard Reflow Soldering. For lead-free processes, the peak temperature should not exceed 255°C (held for 5-10 seconds). The ramp-up speed should be limited to a maximum of 3°C/second.
Q: How is the color temperature sorted? A: Color temperature is sorted into specific bins: UW7-10 (5500K-6000K), UW9-10 (6000K-6500K), and UW11-10 (6500K-7000K). Designers should specify the required bin when placing orders to ensure color consistency.
