DESCRIPTION
The 4800 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 also
be used as a feedback winding in switched mode
power supplies.

A
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.
