NOTES:
1. Typical inductance occurs at the Idc and ETop values shown. 4. Inductance increases with increase in Bop or ETop .
2. The control value of inductance is measured at Bop equal to or less than 10 gauss 5. SIMPLE SWITCHER is a trademark of National Semiconductor Corporation.
without DC current.
3. Inductance decreases with higher values of DC current and increases with lower
values of DC current.
