Web page Sample & buy Tools & software Support & FAQ Document 144-1 bination Line Filter Chokes mon and Differential Mode This series of chokes is intended for use in AC line filters for switching power supplies.They bine mon and differential mode filtering in a single ponent. By using these parts, designers can eliminate two extra filter chokes pared to a standard mon mode choke. The unique bination of special windings and materials provides much better filtering performance than either a mon mode choke or a single winding inductor alone. The differential filtering frequency response is designed to provide filtering at higher frequencies while still allowing the AC line power to pass through without loss. This characteristic is demonstrated in the Differential Mode Attenuation curves.
