MECHANICAL DIMENSIONS  
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

When connecting windings in series, inductance  
will be 4 times the nominal figure shown.  
Specifications typical at TA=25°C  
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.
