1.Tolerance of inductance±15% for 1.2~4.7uH, ±10% for 10~1000uH.
2.Irated is the DC current which cause the inductance drop less than 10% of its nominal inductance without current
and the surface temperature of the part increase less than 45℃.
3.Operating temperature:-20℃ to 105℃ (including self-temperature rise).
