DESCRIPTION

XYYWW

The 4900 series is a range of dual wound

inductors offering ﬂexible options. Windings

have a 1:1 ratio and can be connected in series

or parallel to create a wide range of inductance

combinations. The secondary winding could be

used as a feedback winding in switched mode

power supplies.

Speciﬁcations typical at T_A= 25°C

When connecting windings in series, inductance will be 4 times the nominal ﬁgure shown.

If current is ﬂowing in both windings, the maximum DC current occurs when either the inductance falls to 75% of its nominal value or

when its temperature rise reaches 40°C, whichever is sooner.
