CURRENT (A)  
1. Tolerance of inductance : 15% for 0.8~6.8uH, 10% for 10~1000uH.  
2. Irated is the DC current which cause the inductance drop less than 10% of its nominal inductance without current  
o
and the surface temperature of the part increase less than 45 C.  
o
o
3. Operating temperature: -20 C to 105 C (including self-temperature rise).
