The LPD25-10B heat sink offers a natural convection thermal resistance rating of 17.8 °C/W within a 25mm square footprint. The elliptically shaped, aerodynamic fins are set in a sparse pattern making it easier for air to efficiently flow through the heat sink, making this cooler an ideal choice for either passively or actively cooling high power LEDs.
Made from highly thermal conductive A6063 black anodized aluminum alloy, the fins and the base are forged from one solid piece of aluminum under tremendous pressure, completely eliminating any performance-robbing interface between the base and fins.
The mounting surface of the heat sink is completely smooth and flat, making it most suitable for mounting LEDs using either self adhesive thermally conductive tape, or adhesives.

MODDIY is simply the best in the business for the products they provide. If you plan for shipping from asia, they're faster than you'd expect, and the quality is bar none. 11/10 would shop again!
