Isat : DC current at which the inductance drops 30%(typ) from its value without current.
Irms : The temperature rise current value is the DC current value having temperature increase up 40°C temperature
rise from 25°C ambient.
Operating temperature range ‐40℃ to +105℃ , Electrical specifications at 25℃ .
