1.Tolerance of inductance : M: 20%(1.0~8.2uH) , N: 10%(10~2200uH).
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 C.
3.Operating temperature: -20 C to 105 C ( including self-temperature rise ).
