Common

Mode Line Chokes

Standard Series

High L Series

Coilcraft’s Toroid Style common mode chokes are de-

signed for optimum performance. Their single layer

windings provide for the highest common mode imped-

ance over the widest frequency range.

Spacers, specially designed by Coilcraft, provide 3 mm

creepage and clearance spacings for compatibility with

UL, CSA and IEC safety specifications.

These common mode line chokes come in two series:

Standard and High Inductance. Both are particularly

suitable for switching power supplies operating in the

100-300 kHz range of switching frequencies.

Coilcraft Designer’s Kit P202 contains samples of eight

standard EE and toroidal common mode line chokes. To

order, please contact Coilcraft or purchase on-line at
