NOTES:

1. Typical inductance occurs at the I

d c

and ET

o p

values shown.

2. The control value of inductance is measured at B

o p

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.

4. Inductance increases with increase in B

o p

or ET

o p

5. SIMPLE SWITCHER™ is a trademark of National

Semiconductor Corporation.

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).
