Thermal Interface
THERMAL INTERFACE MATERIAL PART NUMBER GUIDE
All of the heat sinks shown in this catalog are available with any of the following thermal tape and interface materials, pre-applied at the
factory. Use the “T” series, thermally enhanced, pressure sensitive adhesives to attach the heat sink to the electronic package and provide
a good thermal link to the heat sink. The “S” series interface materials have adhesives on only one side, for pre-attachment to the heat
sink, and provide superior thermal performance. Specify these materials in applications where the heat sink will be fixed to the electronic
package by some mechanical means other than a tape. Please note that none of these materials are for use in applications requiring elec-
trical isolation from the electronic device. All options other than -T1 and -T4 are RoHS compliant.
Note: To obtain the estimated thermal resistance of the interface material in your application, divide the thermal impedance value by the
area of the pad in square inches. For example, a 2” x 2” piece of T4 has a resistance of 1.10 C-in^2/W Ö 4 in^2=0.275 C/W

ORDERING INFORMATION
Once you have chosen heat sink and thermal interface material that meets your thermal & mechanical requirements it is easy to
designate the part number. Simply add the interface material suffix referenced on the chart above to the base part number for the
heat sink. The base part number already includes information regarding its size and finish.
Example:
To order the 658 Series heat sink at .350” tall with the T5 thermal interface material, specify part number:
658-35AB - T5
