COILCRAFT BU9

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.
