Coilcraft’s CMT toroid style common mode chokes are
designed to provide the highest common mode imped-
ance over the widest frequency range. These parts are
ideal for any application requiring a high DC current bias
and are well suited for use in switch-mode power supplies.
Common mode chokes are most effective in filtering
supply and return conductors with in-phase signals of
