CURRENT (A)  
1. Tolerance of inductance : 15% for 1.2~4.7uH, 10% for 10~1000uH.  
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).
