Heatsink For SMD LED 1W-3W (High Quality) Without Led

High-quality heatsinks for 1W to 3W SMD LEDs

are typically Aluminum Star PCB base plates designed to draw heat away from the diode to prevent thermal failure. These bases feature high thermal conductivity (often around 1.6 W/mK) and are essential for extending the lifespan of high-power LEDs in applications like flashlights, spotlights, and DIY electronics. 

Standard Specifications:

• Material: High-grade aluminum with anodized surface treatment for durability and corrosion resistance.
• Dimensions: Usually 20mm in diameter (standard star shape) and 1.5mm thickness.
• Thermal Management: Features rapid heat transfer and low thermal resistance welding points.
• Mounting: Includes pre-tinned pads for easy soldering and often has 3mm round screw holes for mounting to larger cooling surfaces.
