1. Tolerance of inductance : +40%/-20% for 1.3~6.8uH, 20% for 12~220uH.
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 to 105 (including self-temperature rise).
