For TO-220, TO-247, and TO-264 devices 

WC Series Heatsinks product image

 

The unique design (patent pending) of the WC Series heat sinks combines a tin plated, solderable, integral cam clip with an compressed ceramic 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.

Features

  • Reduced assembly cost: cam clip and auto-align feature makes fasteners and fixtures obsolete
  • Maximum repeatability: clamping force of the cam clip is not degraded by repeated loading and unloading
  • Great electrical characteristics: ceramic material provides great electrical isolation while offering thermal performance similar to aluminum heatsinks
  • Maximum resistance to shock and vibration: light weight, resilient cam clip locks the component in place and is highly resistant to shock and vibration
