New TTI (Tiger Technologies Inc.) RoHS Compliant Aluminum Heatsinks, Heat Sinks, Part Number A80-0000308-00L, or 210-E185761. Each offer quantity is for a Lot of Forty-Eight (48) Heatsinks. You may offer / buy any number of lots, up to the total quantity available above.

These were purchased at an electronics supplier liquidation earlier this year, and they were brand new in the original factory boxes. We packaged them in heavy Ziplok bags so they will ship fast and cheap. These are either entirely milled, or they were extruded and then extensively milled after extrusion. Whichever way they were made, the resulting product is very precise and very flat. Considering the fin spacing and pattern, they could be used for either forced air (fan cooled) or ambient air (without a fan) applications. Comes with a pair of spring loaded nylon posts that hold the heatsink securely against the device being cooled. Or, if the nylon posts and aluminum ear tabs are not needed, they could be easily snipped off with a pair of side cutting pliers.

The thermal conductive tape patch on the mounting surface is printed with "Parker Sentra Team." Best we can tell, it comes from Parker Hannifin's Chomerics Division. If you need a larger conductive area, we also have Thermagon Heat Conductive Pads that would be perfect for mounting these. Buy now, and get quality name brand heatsinks for less than the cost of cheap imported stuff.

Note: The bags appear to show only two pieces per bag, however, the heatsinks are nested to protect the fins during shipment. There are four (4) pieces per bag, giving you a total of forty-eight (48) pieces per offer.
