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. Weight BU9: 3.1 – 4.1 g BU9H: 3.1 – 4.1 g BU9HS: 3.1 – 3.8 g BU9S: 3.1 – 3.8 g BU10: 6.3 – 6.9 g BU15: 14.6 – 16.1 g BU16: 15.1 – 18.0 g Ambient temperature –40°C to +125°C Storage temperature Component: –40°C to +125°C.
