CMT Series
Common Mode Line Chokes

New RoHS part numbers are shown. Lead was removed from terminations. The last character is now L to indicate RoHS compliance. (View old data sheet.)

Highest common mode impedance over the widest frequency range.
1250 Vrms isolation between windings.
Inductance values up to 125 mH.
Current ratings as high as 15 Amps.
Creepage and clearance = 3.2 mm
RoHS-compliant. Tin-silver over copper terminations.
