CURRENT (A)
1. Tolerance of inductance: 1.5~331uH 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
4. Operating temperature: -20 C to 105 C (including self-temperature rise).
