S802-3750-145

The Clear Lake Series

Round Pin Heat Sink with Push Pins

37.5 X 37.5 X 14.5 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)
  • Secure attachment to PCB using push pins or shoulder screws
  • 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)
  • RoHS compliant
  • Cost effective

Thermal Interface Material and Attachment Hardware

  • We recommend using spring-loaded push pins or shoulder screws to secure the heat sink to device.
  • We recommend Chomerics T725, T557 or Laird Tpcm 585 as interface materials.
