Common Mode Line Chokes – CMT
CMTs feature inductance values up to 125 mH and Irms
ratings as high as 15 Amps.
•1250 Vrms, one minute isolation between windings
•Industry standard footprint.
•Creepage and clearance = 3.2 mm
•UL1446 Class B (130°C) Insulation System
(UL File E83628)
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.
