CURRENT (A)

1. Tolerance of inductance: 30% for 10~82uH, 20% for 100~820uH, 10% for 1000~3900uH.

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).
