The Great Lakes Series
Precision Forged Round Pin Heat Sink
40 X 40 X 20.0 mm
Features and Benefits
- Designed for low-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 and REACH compliant
- Cost effective

Thermal Interface Material and Attachment Method
- S807 series is designed to work with many attachment methods, including captive screws, push pins and double-sided thermal tapes.
- Captive screws (made of stainless steel) provide the most secure attachment and are recommended for large and heavy heat sinks.
- Push pins (made of spring steel or nylon) provide a convenient way to install heat sinks to printed circuit boards.
- Double-sided thermal tapes provide strong adhesion between heat sinks and devices. Because of their relatively high thermal resistance, we only recommend thermal tapes on cost-sensitive projects.
- When captive screws and push pins are used, we recommend phase change materials, such as Chomerics T7xx and Laird Tpcm series, as the thermal interface materials (TIM).
