B5W Series
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.
