S803-4500-095

The Pikes Peak Series

Cold Forged Elliptical Pin Heat Sink

45 X 45 X 9.5 mm

 

Features and Benefits

  • Designed for medium- to high-airflow environment (200-1000 LFM, or 1.0-5.0 m/sec)
  • Forged from highly conductive pure aluminum (240 W/m-K)
  • Low pressure drop (improving downstream velocity and temperature fields)
  • Overall height can be customized (without increasing cost)
  • Secondary operation available (to modify shape, add holes, eliminate or shorten certain pins, etc.)
  • RoHS compliant
  • Cost effective
