Toroidal Common Mode Line Chokes

Standard & High L Series

RoHS compliant
  • Available in two 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
  • UL1446 Class B (130°C) Insulation System (UL File E83628)
  • Creepage and clearance = 3.2 mm
  • Refer to Designing Common Mode Filters for design guidance.
  • RoHS-compliant. Tin-silver over copper terminations.
  • Samples of several values are available in Coilcraft Designer's Kit P402
