Litz Wire

Litz wire is primarily used in resonant circuits where high efficiency is required. Bay Associates' line of Litz wire constructions are designed for use over extra low frequency through high frequency ranges. Utilizing a wide range of strand sizes and a large variety of magnet wire film insulations, Bay Associates can design a Litz conductor to meet your specific design requirements.


  • Reduction of proximity effect and AC and eddy current losses
  • Uniform current flow
  • Reduced power losses due to high Q (efficiency) factor
  • Solderable film insulations
  • High temperature ratings
  • Decreased AC resistance
