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, TO-247, and TO-264 packages. These self-aligning heat sinks feature solderable feet and an integrated clip with 13.2 (lbf) of force on the center of the device to enhance thermal performance.


• Reduced Assembly Cost: spring clip and auto-align feature makes fasteners and fixtures obsolete, along with stray metal filings from tapped holes.
• Maximum Repeatability: clamping force of the clip is not degraded by repeated loading and unloading.
• Maximum Heat Transfer per Unit Space: maximum surface area per unit volume and consistent mounting force reduces thermal resistance
• Maximum Resistance to Shock and Vibration: lightweight, resilient clips lock the component in place and are highly resistant to shock and vibration
• Maximum Reliability: helps prevent short circuits by eliminating metal particles from thread tapping
• RoHS compliant
