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.
APPLICATION NEED:
• Maximum Performance
• Low Pressure Drop
• Fits industry standard Eighth Brick modules
• Optimal configuration
• Simple assembly
FEATURES AND BENEFITS:
• High fin density has more surface area
for heat transfer, despite small foot print.
• Thin fin geometry improves system airflow
and reduces fan costs.
• Hole pattern fits 1/8 brick DC/DC Converters from
top manufacturers like Delta, Emerson and Tyco
• Lengthwise and crosswise fin orientations in three
fin heights to allow a precise match to the application
• High performance QPad3TM interface pad saves
time and optional hardware kit provides the
complete solution under a single part number
