      >"** The TO220 heatsinks in the pic are only good for a couple of watts in       free air - so device dissipation is low"              With all them pictures in there who knows exactly what you're getting ? Is it       5 of the finned pieces and 5 of the ones bent in a rectangle ?              >"Device temp will only vary a few degrees using different mounting       interfaces. "              Yeah, because they're not dissipating shit. There isn't enough square area       there to make it even worth figuring out. I wouldn't go over about double free       air with those. And if they sit down flat on a PC board that will impede the       airflow.              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
