  • For active power factor correction
  • Vertical winding technology
  • Low parasitic capacitance
  • Lowest ohmic loss
  • High efficiency


Tecnical DataPFC chokes are inductive components, which must have a low-capacitance arrangement. In switched-mode power supplies they work in series with the supplying mains voltage, improve the power factor of electrical devices, and fulfil the statutory requirements regarding the medium-frequency interference emissions associated with the device.

Advantages of the flat copper winding

  • Single-layer winding
  • Absolute low-capacitance winding
  • Smallest RDC for maximum efficiency
  • Less heating
  • Smaller design, lighter component
  • Minimised interference potential
