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

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