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

2. Isat is the DC current which cause the inductance drop to Li.

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

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