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