DC BIAS (A)

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

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

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

4.Operating temperature : -20OCto 105OC ( including self-temperature rise ).
