CURRENT (A)

1. Tolerance of inductance : 2 0%.

2. Irated is the DC current which cause the inductance drop less than 20% 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).
