DESCRIPTION

The 4900 series is a range of dual wind

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.

1 When connecting windings in series, inductance

will be 4 times the nominal figure shown.

2 Specifications typical at TA=25°C

3 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.
