1.Tolerance of inductance: 30%.

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).
