Material: Aluminum, Black Anodized.

Keep your "half brick" size AT&T and Computer Products power modules cool with these effi-

cient black anodized aluminum heat sinks made for natural or forced convection applications.

To include four M3 x 8mm Phillips head SEM attachment screws, add an “M” suffix to stan-

dard part number. To specify factory applied Deltalink IV thermal interface material, add an

“S4” suffix to standard part number. Deltalink IV is a non-insulating graphite based material

used as a clean, thermally efficient alternative to thermal grease.
