Trying to understand a datasheet of a NTC, Murata NXFT15XH103FEAB021. They specify the beta/B value, very good, I understand how to calculate temperature / resistance with it.

But they also mention other B-Constants as "Reference Values" for different temperature ranges. I don't understand what they want to tell me with them. Can anyone explain?

@electronic_eel I'm gonna guess chose the right B depending on the max temperature in your target application. So if your temp range is 25-50º , you should assume the firts B they list there at 3380K.

But if your target temp range is 25-100º, the B you should work with should be that last, largest one at 3455K?
