COMMON MODE CHOKE FOR IEEE 1394 APPLICATIONS

DESCRIPTION

The B5W is a dual wound common mode choke ideal for common mode noise attenuation in twisted pair cable interfaces as well as IEEE 1394 applications. An excellent impedance balance between two sets of twisted pairs is achieved by winding across a single core. One B5W common mode choke coil per interface port is possible with this dual winding configuration.
