[Elecraft] OT: heat sinking resistors

[Craig D. Smith]

Hi Vic ...

My first inclination would be to go to the Ohmite website and look at the
datasheet for the resistors and search for any application notes.  One or
both of these sources should address, at least in relative terms, how much
heat is typically removed via conduction through the leads vs. from the body
of the resistor.  At these power levels, thermal considerations must have
been part of the mechanical package design of the device.  If you are lucky,
you will find something like a graph of thermal resistance through the leads
vs. PCB trace area, airflow or some other variable under your control.  Good
luck!
