Würth Elektronik Automotive Cable Ferrites

Meeting the demands of motor vehicle electrification

Würth Elektronik offers four different series of cable ferrites which are capable of meeting all requirements for your automotive applications.

The rising electrification of motor vehicles is inevitably accompanied by an increase in electromagnetic interference. The use of cable ferrites can significantly reduce these in electric vehicles, whether interference signals on lines or electromagnetic field coupling effects. High-performance inductive materials in cable ferrites significantly improve EMC performance.

Standard ferrite cable core suppression elements in axial as well in toroidal form are suitable for a wide range of applications with medium and high frequencies. For higher frequencies, these contain a magnesium component.

A very wide frequency range is covered by cable ferrites with a new nanocrystalline material (NC).

EMI Suppression for Medium-High Frequency Range

WE-AEFA ring core is an EMC cable ferrite suppressor in an axial and toroidal form, specifically designed for a variety of applications. The special spectrum suppression is for medium and high frequency noise. It is also available in larger designs.

EMI Suppression for Higher Frequency Range

WE-TEFA ring core is an EMC cable ferrite suppressor with a component of Mg. The impedance supports a higher frequency than a standard type.

EMI Suppression for Medium-Low Frequency Range

WE-TEMA ring core is an EMC cable ferrite suppressor specially designed for the medium frequency range with very high suppression.

EMI Suppression for a Wide-Band Spectrum

WE-AENA cable ferrites with the latest NC core (nanocrystalline) material technology to provide noise suppression across a very wide frequency range. Available in many different standard sizes.

Applications

  • Wires
  • Coaxial cables
  • Wire-wrapping cables
  • Multiconductor wires
  • EMI suppression against Inverter spikes

 

  • Attenuate EMI noise induced by the rotor of the electric motor
  • Minimize NVH (Noise vibrations harshness) in the EMC spectrum at power train
  • Special EMI suppression for the junction box interconnections
