1. Tolerance of inductance : +30%/-20% for 0.82~8.25uH, 20% for 10~1000uH.

2. Irated is the DC current which cause the inductance drop less than 25% of its nominal inductance without current and the surface temperature of the part increase less than 45 C.

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