CombinationLineFilterChokes
Common and
Differential Mode
This series of chokes is intended for use in AC line filters
for switching power supplies.They combine common and
differential mode filtering in a single component.
By using these parts, designers can eliminate two extra fil-
ter chokes compared to a standard common mode choke.
The unique combination of special windings and materials
provides much better filtering performance than either a
common mode choke or a single winding inductor alone.
The differential filtering frequency response is designed
to provide filtering at higher frequencies while still allow-
ing the AC line power to pass through without loss. This
characteristic is demonstrated in the Differential Mode
Attenuation curves.
