Toroidal Common Mode Line Chokes – Standard & High L Series

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.)

  • Available in 2 series: standard inductance and high inductance
  • Single layer windings provide highest common mode impedance over the widest frequency range
  • Ideal for switching power supplies in the 100 - 300 kHz range of switching frequencies
  • RoHS-compliant. Tin-silver over copper terminations.
  • Samples of several values are available in Coilcraft Designer's Kit P402
