1. Tolerance of inductance: 20% for 1.0~6.8uH, 10% for 10~470uH.
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 45
3. Operating temperature : -20

to 105

(including self-temperature rise).
