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
filter 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.
