  Customization
  • Ultracool III heat sinks can be customized to any height.
  • UltraCool III heat sinks can be customized to any footprint.
  • The majority of alterations do not require any tooling or setup charges.
  Pin Configurations
 
  • Three pin configurations are available. Each configuration is designed to operate optimally in a specific airspeed range.
Configuration Description Airflow Min Airflow Max
M** Low Pin Density 0* 150*
U Moderate Pin density 150* 400*
R High Pin density 400* 600*
*Airflow is expressed in LFM (Linear Feet per Minute).
**Part numbers ending with an M.
  Attachment Methods
  • Standard and custom mechanical clips – For More
  • Pre-applied thermal tape. Suitable for metal, ceramic and plastic packages.
  • Mounting holes, threads and any other secondary operations.
  Manufacturing Technology & Metallurgy
  • UltraCool III heat sinks are forged from pure aluminum, a highly conductive alloy that is up to 100 percent more conductive than AL 380 (a common casting alloy), and up to 40 percent more conductive then AL6061 (a common extrusion alloy).
  • The nature of the cold forging process ensures that no air bubbles, cavities or any other impurities will exist within the product or on its exterior.
  Finishes
  • Sulpheric Anodize - black, red or clear.
  • Conversion Coating (Alodine) - yellow or clear.
  • Nickel (electroless or electrolytic).
