Heat Sinks for Eighth Brick
RoHS
Compliant
DC/DC Converters
STANDARD THERMAL SOLUTIONS
FOR EIGHTH BRICK CONVERTERS
Aavid Thermalloy heat sinks are designed for engineers
seeking a complete off-the-shelf cooling solution for
industry standard eighth brick converters. Unlike other
converter heat sinks, Aavid designs feature thin fin
geometry which increases thermal performance and
reduces pressure drop. In addition, all heat sinks are
ready for mounting with interface material pre-applied
which streamlines procurement and assembly.
