CURRENT (A)

1. Tolerance of inductance :

K : 10% for 0.12~100uH.

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).
