Arcol Ohmite Heatsink, TO-252, TO-263 and TO-268, 12.7 x 40.13 x 11.68mm

The Arcol Ohmite Heatsink D Series heatsinks provide an innovative solution for SMT compatible semiconductors and resistors. The unique design (Patent Pending) combines tin plated, solderable rods with an aluminium extruded heat sink body. These rods (or “rollers”) are mated mechanically to the heatsink by forging to reduce the thermal resistance between the heatsink body and the solderable feet.

Increased surface areas by 3 times therefore thermal performance up to 300% over the aluminium stamped heat sinks on markets
Light weight aluminium construction allows faster pick and place assembly reducing the manufacturing cycle time
Radius mounted “Rollers” are designed for maximizing heat transfer from the component and avoiding the thermal “bottle-neck” seen in stamped and staked
Available in tape and reel
RoHS Compliant
