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. The 9th and 10th digits define
the PC board mounting method, and the 11th and 12th digits define the method of attachment of the package to the heat sink. For digits
8,9,10,11 and 12, the absence of any of those options is always designated by a zero in those positions. Important NOTE:The 12 digit part number
sequence is a general format. Due to the different variations and styles of heat sinks, we have included an Option Index on pages 82–84 to show
available options and accessories for the products covered in this catalog.
A = Base Part Number
B = Package Style
C = Finish
D = Interface Material
E = PC Board Mounting
F = Package Mounting
