1. Lo is the initial inductance and the tolerance is 20%.

2. Isat is the DC current which cause the inductance drop 20% of its nominal inductance without current.

3. Irms is the DC current which cause the surface temperature of the part increase approximately 45 C.

4. Operating temperature : -20 C to 105 C ( including self-temperature rise ).
