CURRENT (A)  
1. Tolerance of inductance: 20%.  
2. Irated is the DC current which cause the inductance drop 10% typical 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).
