1. Tolerance of inductance: 30% for 2.2~8.2uH; 20% for 10~22uH.
2. Isat is the DC current which cause the inductance drop 35% typical of its nominal inductance without current.
3. Ir is the DC current which cause the surface temperature of the part increase less than
4.Operating temperature : -20 to 105 (including self-temperature rise).
