Yes, I suppose for the amateur builder, applying power to your design in and finger testing is an option. If it doesn’t burst into flames, I suppose its ok? (In commercial designing we don’t often have that option so we’ll have to stick to our calculus). It might be wise to invest in one of those IR temperature guns from Harbor Freight Tools for $20 to save your fingertips though!
For LP design work at the approx.. 10 watt level… this just isn’t gonna be an issue unless you are using the wrong filter for the band and the filter is dissipating all of the power. Once you get to the kW+ region… best use your math.
Like I said in my original note, if you are uncomfortable with the math, there are many calculators on the internet that work. Just google them.
To be clear about the specification… it says that you would be operating at 0.1% of the full/ capable dissipation properties of the capacitor if it were used in a 50 VRMS circuit at 1 MHz Using this one data point, you can translate that to any voltage/ frequency point and ratio it to this point to determine what % of dissipation you are operating (designing) at.

I find that train of thought rather confusing.
