hfe of transisor BC548B

Hi, I'm a bit confused from the datasheet of transistor BC548B I want to know beta or hfe of this transistor, but it is confusing from looking at the datasheet below.

BC548B Datasheet

Can you have 2 values for hfe?

Thanks

actually you have many more, the hfe changes with temperature, output current etc.

There are some reasons of this variation.
First, hfe is not very tightly controlled parameter, because wafer to wafer some process parameters show quite large deviations from nominal value that's why hfe is changed in a large region.
Second, hfe is tightly dependent on collector current and it has a maxima and two minimas.
Third, eventough BC548B is industry standard BJT, it's manufactured by different companies and that's why it has some different process parameters and variable.

Design you circuit with the lowest expected Hfe, check that it does not fall apart with the max Hfe.
