Document 260-1 Common Mode Chokes – BU Series These low cost, high performance choke coils are designed to virtually eliminate line conducted common mode noise. The BU9S and BU9HS families are ideal for signal line applications; the others can be used in switching power supplies and power supply circuits. All provide significant attenuation of common mode noise across a broad range of frequencies. For height-restricted applications, the BU9 and BU9S filters are available in a horizontal configuration, which reduces their height to under half an inch (12.5 mm). For free evaluation samples, contact Coilcraft or request them on-line at www.coilcraft.com. Core material Ferrite Terminations RoHS compliant tin-silver over copper. Other terminations available at additional cost.
