Ordering code
The shape and hole pattern of the heat sink will determine the shape and hole
pattern of the pad. If you are ordering a heat sink which mounts to a semicon-
ductor on both sides, the ordering code for two pads should be used. To order

KonDux? / Grafoil? Conducta-Pad**
Kondux? interface pads are a cost effective
alternative to thermally conductive grease
compounds. Kondux? pads are electrically
conductive and ideal for use with small,
