Common Mode Line Chokes - CMT Series
Coilcraft’s CMT toroid style common mode chokes are
designed to provide the highest common mode impedance 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.
equal amplitude. Differential mode inductors are available
for filtering out-of-phase or uneven amplitude signals.
CMTs feature inductance values up to 125 mH and Irms
ratings as high as 15 Amps.
• 1250 Vrms isolation between windings
• Industry standard footprint.
• IEC, UL, and VDE compliant.
Common mode chokes are most effective in filtering
supply and return conductors with in-phase signals of
