Pack of Ten TO-220 Aluminium Heatsinks

This pack supplies ten silver aluminium heatsinks sized 25 x 15 x 11 mm for TO-220, TO-3P and TO-247 packages. They suit hobbyists and repair technicians cooling 7805 regulators, MOSFETs or similar discrete semiconductors.

M3 Mounting and Compact Footprint

Each piece weighs four grams and carries an M3 screw hole for direct bolting to the component tab. The low 11 mm height and 15 mm width leave room on dense boards where larger extrusions would foul adjacent parts.

Ten-Piece Lot for Batch Assembly

The quantity of ten matches small production runs or a spares bin without forcing a bulk purchase. Buyers needing only one or two heatsinks, or a different package footprint, should look elsewhere.
