1. Tolerance of inductance: 15% for 1.0~8.2uH, 10% for 10~100uH.
2. Isat is the DC current which cause the inductance drop less than 10% of its nominal inductance without current.
3. Ir is the DC current which cause the surface temperature of the part increase less than 45
4. Operating temperature : -20 to 105 (including self-temperature rise).
