Common Mode Line Chokes – CMT
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 sup-
ply 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, one minute isolation between windings
• Industry standard footprint.
• Creepage and clearance = 3.2 mm
• UL1446 Class B (130°C) Insulation System
