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.

spring 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
Unit Space: maximum surface
area per unit volume and con-
sistent 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
