1. Tolerance of inductance : +40%/-20% for 0.75~7.4uH, 20% for 10~1000uH.
2. Irated is the DC current which cause the inductance drop less than 20% of its nominal inductance without current
and the surface temperature of the part increase less than 45 C.
3. Operating temperature : -20 to 105 (including self-temperature rise).
