Ok, but given they all run steady state at the same temperature, then is that where the Joules spec comes in? Which can take the heat better-- a 200J or a 300J one? Or is it that dissipation figure that matters? The 020 and 025 have the same dissipation constants and the same thermal time constants.
What is that black stuff anyway and is bigger, fatter, more black stuff better for heat tolerance? The 020 and the 025 have the same diameter but the 025 is 6.3 vs 6.0 thick for the 020, so the 025 is fatter.
The 020 is 206C at mx current while the 025 is 236C at max current. But they have different max currents 20 and 25. The converter's current is say 13a at full bore. 13 is less of 25 than it is of 20 but it might be at the same temp as suggested, which would be less of 236 than of 206.
