CURRENT (A)

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 45oC.
3. Operating temperature: -20oC to	105oC (including self-temperature rise).
