Extruded collar style heat sink
with mounting hole for hardware
attachment to the circuit card. The heat
sink includes a mount boss that will
accept a 4-40 screw for secure mounting
in high vibration environments. The split
collar design provides a press fit between
the transistor and the heat sink creating
an excellent thermal conduction path.
