1. Tolerance of inductance: 20% for 10~27uH, 15% for 33~82uH, 10% for 100~270.
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).
