If we look at the worse case current for the 5 ohm thermister, it would allow approximately 170 volts peak divided by 5 ohms or 34 amps of initial current to flow.
If we look at the worse case current for the 2 ohm thermister, it would allow approximately 170 volts peak divided by 2 ohms or 85 amps of initial current to flow.

I know there was the single cycle value being different from actual current (but can't remember in what way ) but how about that 34a limit for the 5R compared with this spec for the converter at 40a?
•MAX INRUSH CURRENT, SINGLE CYCLE: 40 AMPS
Could the 40a translated into real amps be too much for the 34a 5R and ok for the 85a 2R?
