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.
