CURRENT (A)
1. Tolerance of inductance: 
20% for 10~27uH, 
15% for 33~82uH, 
10% for 100~270.
2.Irated is the DC current which cause the inductance drop 10% typical 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).
