Web Sample Tools & Support Document 260-1 page & buy software & FAQ Common Mode Chokes BU Series AEC These low cost, high performance choke coils are de- + Q200 85C signed 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 termina- tions available at additional cost.
