CURRENT (A)

1. Tolerance of inductance :

M : 20% for 1.0~8.2uH, K : 10% for 10~560uH.

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).
