S801-1900-245

The Crater Lake Series

Cold Forged Round Pin Heat Sink

19 X 19 X 24.5 mm

 

Features and Benefits

  • Designed for low- to medium-airflow environment (good for natural convection, limited airflow, fan failure, highly populated PCB, etc.)
  • Forged from highly conductive pure aluminum (240 W/m-K)
  • Omni-directional (allowing air to come from any direction)
  • 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
