I want to use a 24V to 5V DC converter, the PYBJ10-Q24-S5 (https://www.mouser.fr/datasheet/2/670/pybj10-om-1548233.pdf).
So if I'm correct, in the worst case scenario it should not exceed 558mA.
I was planning to use a resettable fuse. If I understood correctly, the holding current is the maximum current such as the fuse won't trip.
The tripping current is the minimum current such as the fuse will trip.
In conclusion, I have to choose a resettable fuse with a holding current = 508mA and a tripping current = 558mA.
Problem is : in this configuration, I can't find exactly the right fuse.
Knowing all this, how do I choose my fuse from all the existing models?
For example, I found some fuses with currents of 550mA versus 1A but I'm afraid that 1amp is much too high for my converter.
I guess I'm missing something.
