Copper Pin Fin Heatsinks Cool SMDs Through Improved Conductivity

The UltraCool IV series of pin fin heatsinks is forged from highly conductive oxygen-free copper. This metal exhibits a thermal conductivity that's 20% better than pure aluminum and 40% greater than popular aluminum extrusion alloys. Effective with airflows ranging from 100 to 400 LFM, the heatsinks are available in footprints of 0.25 by 0.25 in. to 1.5 by 1.5 in. with heights of 0.15 to 0.8 in. Pin diameter ranges from 0.06 to 0.125 in.

Pricing ranges from under $1 to $4.50 in production quantities.
