The unique design (patent pending) of the W Series heat sinks
combines a tin plated, solderable, integral spring clip with an
extruded aluminum heat sink body for an all-in-one solution to
through-hole mounting of TO-220 or TO-247 packages. These
self-aligning heat sinks feature solderable feet and an inte-
grated clip with 13.2 (lbf) of force on the center of the device to
enhance thermal performance.

clip and auto-align feature
makes fasteners and fixtures
obsolete, along with stray metal
filings from tapped holes
ing force of the spring clip is not
degraded by repeated loading
and unloading
Space: maximum surface area
per unit volume and consistent
mounting force reduces thermal
resistance
and Vibration: light weight,
resilient spring clip locks the
component in place and is highly
resistant to shock and vibration
vent short circuits by eliminating
metal particles from thread tap-
