EMC Common Mode Filter – SMTB Series
SMTB Series
SMTB Series 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 signal core. One SBCB
common mode choke coil per interface port is possible with this dual
winding configuration.
