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).
