Air Cooled Heatsinks

High Performance Heatsinks

Hollowfin® Heatsink

The Hollowfin® heatsink is characterized by the shape of its fins which when mounted on the DF (6.86 mm) baseplate effectively duplicates the high fin density MF (3.43 mm) series, but with taller fins. A height to space ratio equivalent to 46:1 occurs when the fin height is 118 mm. The Hollowfin® is an ideal candidate to be attached to a copper baseplate to maximize performance. No glue is used in the process.
