Inductance increases with increase in Bop or ETop. 1. Typical inductance occurs at the Idc and ETop values shown. 5. SIMPLE SWITCHER™ is a trademark of National Semiconductor Corporation. 2. The control value of inductance is measured at Bop equal to or less than 10 gauss without DC current. 3. Inductance decreases with higher values of DC current and increases with lower values of DC current. 6. RoHS compliant parts are available. Order RoHS compliant parts by adding the suffix “NL” to the part number (i.e. PE-53112 becomes PE-53112NL).
