1. Tolerance of inductance: 15% for 3.9~8.2uH, 10% for 10~47uH.
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 45
3. Operating temperature : -20 to 105 (including self-temperature rise).
