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 P402 contains samples of
eight standard EE and toroidal common mode line
chokes. To order, please contact Coilcraft or purchase
