1.	L is the inductance of each phase (1-4 @ 2,3 open or 2-3 @ 1,4 open) @100KHz, 1V, 25OC.
2.	2*Lk is two times of leakage inductance (1-2 @ 4,3 short)

3.Isat1 is the DC current which cause the L drop to L @ lsat1.(The unbalance current of both phase should smaller than Isat1.)

4.Isat2 is the DC current which cause the 2*Lk drop to 2*Lk @ lsat2.

5.Operating temperature : -40OCto 125OC ( including self-temperature rise ).
