Extruded heat sink with large radial fins
Extruded heat sink with large radial
fins features equal channel widths on
both sides for single or dual device
mounting. Includes two solderable
mounting pins which permit vertical
mounting and eliminate stress on
device leads. Available in four heights
for TO-220, TO-218, and TO-247 devices.
