PRODUCT OVERVIEW
The 4700 series is a range of dual wound
inductors offering flexible options. Windings can
be connected in series or parallel to create a
wide range of inductance combinations. They can
also be used as common mode chokes or 1:1
transformers with the secondary winding used
as a feedback winding in switched mode power
supplies.

A
1 When connecting windings in series, inductance will be 4 times the nominal figure shown.
2 If current is flowing in both windings, the maximum DC current occurs when either the inductance falls to 85% of its nominal value or
when its temperature rise reaches 40°C, whichever is sooner.
