EV EMI suppression
EMC noise cancellation for new EV & HEV applications
EV EMI suppression
EMC noise cancellation for new EV & HEV 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 and hybrid 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).

Applications matrix
We offer the complete frequency range
Würth Elektronik cable ferrites are designed to work in all different frequency ranges with best attenuation.
It is essential for the following automotive applications:
- In 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
Würth Elektronik offers four different series capable to meet all requirements for your application:
Cable ferrite for all different EMI suppression scenarios
EMI suppression for medium-high freq. range
WE-AEFA ring core is an EMC cable ferrite suppressor in an axial as well in toroidal form, special designed for many kinds of applications. The special spectrum suppression is for medium and high frequency noise. Also available in larger designs.
EMI suppression for higher freq. 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 freq. 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
