1. Lo is the initial inductance and the tolerance is 20%.
2. Isat is the DC current which cause the inductance drop approximately 20% of its nominal inductance without current.
3. Irms is the DC current which cause the surface temperature of the part increase less than 45^OC.
4. Operating temperature : -40^OC to 125^OC ( including self-temperature rise ).
