S804-450L-279
The Kings Peak Series
Elliptical Pin Heat Sink with Push Pins
45 X 45 X 27.9 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)
- Secure attachment to PCB using push pins or shoulder screws
- 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

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.
