Extruded heat sink with unequal
channel widths front and back
can accommodate a TO-220, TO-218,
or TO-247 devices. Includes two solder-
able mounting pins which permit verti-
cal mounting and eliminate stress on
device leads. Available in three heights.
Version without hole uses clip 5901
(sold separately) to attach device.
See page 97 for clip information.
