Applications Used

Reviewer: from GRAWN, MI USA

I have used this heatsink without any problems on the TO-220 form for the LM317 and similar voltage regulators. No measurements were taken but the specs quoted by the earlier comment roughly match observations.

Great deal

Reviewer: from EAST TAWAS, MI USA

These are real nice units, though they will not directly fit a TO-220 device if it has a thin tab. You will have to bend in the heat sink fins to make it clamp tight on the thin tab.
Here are some specs from a very similar unit:
Power Dissipation @ Temperature Rise 1.5W @ 40°C,
Thermal Resistance @ Forced Air Flow 7.0°C/W @ 400 LFM,
Thermal Resistance @ Natural 27.3°C/W,
