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).
