1.Tolerance of inductance: Features 30% for 2.2~8.2uH; Mechanical Dimension: 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 45oC.

4.Operating temperature : -20oC to 105oC (including self-temperature rise).
