Combination Line Filter Chokes Document 144-1 Document 144-1 Revised 02/03/16 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.
