... How to decipher an Aavid standard 12 digit part number Aavid Thermalloy's standard product line in most cases consists of a 12-digit part number sequence. In most standard offerings, Digits 1 through 4, define the model basic part number. Digits 5 and 6 designate the package style that a particular heat sink is designed to cool. The 7th digit deter- mines the finish, and the 8th identifies the interface material, if one can be used for that particular style heat sink ...

... How to decipher a Thermalloy origin part number? Aavid Thermalloy features a variety of Thermalloy origin standard products that consist of a different part number sequence than the standard Aavid 12 digit part numbering system. In most cases, digits 1 through 4, designate the basic model number of the heat sink. Digits 5-6, designate the finish of the heat sink. Digits 6-13 can designate any number of different options that come with a specific model number. (Please refer to Option Index D on page 85 to see Aavid Thermalloy‘ ...
