1. Tolerance of inductance:

20% for 1.0~220.0uH.

2. Isat is the DC current which cause the inductance drop 30% typical of its nominal inductance without current.

3. Ir is the DC current which cause the surface temperature of the part increase less than 40

4. Rated current : Value obtained when current flows and the temperature has risen to 40

flows and the nominal value of inductance has fallen by 30%, whichever is smaller.

5. Operating temperature: -40 C to 125 C (including self-temperature rise).
