Applications Used
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
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,
