CURRENT (A)
1. Tolerance of inductance: 30%
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 45oC.
3. Operating temperature : -20oC to 105oC (including self-temperature rise).
