1.

Tolerance of inductance :

+40%/-20% for 1.2~7.6uH, 20% for 10~1000uH.

2.

Irated is the DC current

which cause the inductance drop less than 25% 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).
