S802-2700-279
The Clear Lake Series
Round Pin Heat Sink with Push Pins
27 X 27 X 27.9 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 Method
- 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.
