3257, 3260
Extruded collar style heat
sink with radial fins. The split
collar design provides a press fit
between the transistor and the
heat sink creating an excellent
thermal conduction path.
Available in two heights.

Extruded collar style heat sink with
swept back fins for increased surface
area in a small volume. The split collar
design provides a press fit between
the transistor and the heat sink creating
an excellent thermal conduction path.
Available in two inside diameters.
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.
