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 45OC.
4. Operating temperature : -40OC to 125OC ( including self-temperature rise ).
