Document 326-1 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. 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.
