The unique design (patent pending) of the WC Series heat sinks combines a tin plated, solderable, integral spring 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.


  • Reduced assembly cost: spring clip and auto-align feature makes fasteners and fixtures obsolete
  • Maximum repeatability: clamping force of the spring 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 spring clip locks the component in place and is highly resistant to shock and vibration
