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
4. Operating temperature : -40
