Nanocrystalline Common Mode Chokes with a compact design and
technical advantages vs. Ferritcore chokes

Nanocrystalline suppressor chokes have already found their
place in the automotive sector due to their extremely compact design and excellent attenuation properties. Now they are becoming increasingly interesting in industrial applications when it comes to broad frequency spectra, low losses and low temperature dependence. For example, earlier external filters

can be replaced by integrated compact Nano-chokes in converter applications. Typical areas of application are: switching power supplies, solar inverter, wind generator, welding equipment, frequency converter.

Other advantages vs. Ferritecore chokes:

 
  • Small design due to high permeability
  • Small number of turns (small winding capacity, small copper losses)
  • High attenuation over large frequency range
  • Constant impedance over a wide Icm-range
  • Attenuation property very stable over temperature
  • No magnetic reversal at 200°C
  • Normal working temperature does not have to be considered in the design (70°C)
  • Low noise, NF and HF range
  • Low magnetostriction
  • Robust with mechanical load
  • HF-interference current is absorbed and not reflected
  • High saturation induction 1,2T (interference pulses can saturate common mode chokes)
