1. Tolerance of inductance: 20% .
2. Isat is the DC current which cause the inductance drop less than 25% of its nominal inductance without current. ( 30% Typ. for SIQ73C)
3. Ir is the DC current which cause the surface temperature of the part increase less than 45
o
C.
4. Operating temperature: -20
o
C to 105
o
C (including self-temperature rise).
