PRODUCT OVERVIEW

XYYWW

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.

Speciﬁcations typical at T_A= 25°C

ꢀ

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.
