wattage ratings to avoid permanent damage from over-heating.

Some power resistors are only specified for claimed power
dissipation at minus 100C!

Care to point to a datasheet that shows that?

http://www.resistorsonline.com/wire-wound-resistor.html


But the table on that page is clearly headed "Rating at 70°C"!

There are 3 derating lines shown. How do you make sense of them?

For temps over 70C.
