1. Tolerance of inductance:
2. Irated is the DC current which cause the inductance drop 35% 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).
30% for 1.0~8.2uH, 20% for 10~47uH.
