1. Tolerance of inductance: 30%.

2. Isat is the DC current which cause the inductance drop less than 35% of its nominal inductance without current.

3. Ir is the DC current which cause the surface temperature of the part increase less than 45

oC.

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