1. Tolerance of inductance: 20% for 10~27uH, 15% for 33~68uH.
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).
