CURRENT (A)

1.Tolerance of inductance : Manual background15% for 1.0~8.2uH, Manual background10% for 10~68uH.

2.Irated is the DC current which cause the inductance drop less than 10%(20% for A-3R3 & A-4R7) of its nominal inductance without current and the surface temperature of the part increase less than 45oC.

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