The Half Dome Series
Plate Fin Heat Sinks for Low to Medium Airflow
220 X 200 X 18.0 mm
Features and Benefits
- Plate fin heat sinks are manufactured by extrusion using highly conductive aluminum alloy 6063-T5, which has great mechanical and thermal properties.
- The tooling and unit costs of extrusion are among the lowest of all mass-production methods.
- Extruded aluminum heat sinks can be easily customized with excellent surface finish and appearance.
- To improve thermal radiation, heat sinks can be anodized to black or other colors.
- Length can be customized (without increasing costs).

Thermal Interface Material and Attachment Method
- We recommend thermal grease and phase change materials when mechanical hardware is used to attach this heat sink to a device.
- Thermal tapes such as 3M 8810 and MHS T302 can be used when mechanical hardware is not available.
- When this heat sink is used to cool multiple devices, compressible thermal pads are recommended.
- For other attachment methods and TIMs, please contact us.
