A recent post mentions various models of Balun or Choke with power
ratings of, variously 3kW or 5kW.
How are those ratings derived?
Is it "run X power into a matched dummy load" and the thing doesn't
overheat (by some TBD measure)?
Is it by computation from the breakdown voltage or current carrying
capacity of the wires (probably without allowing for the thermal design
of the package)?
Is it "I ran a Henry 5k through it at max power into my antenna and it
seemed ok"?
And then
what would be a "real" objective power rating method? Seems that one of
the key factors is the dissipation of whatever you're choking, although
if the Z is high enough, maybe that's insignificant.
