Common Mode Line Chokes - CMT Series
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
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.
