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 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 allowing the AC line power to pass through without loss.
