Metal Core: MPTR Series

Normal-mode noise suppressing core with excellent DC superposition property.

  • Due to higher magnetic flux density, current superposition (current at 20A or less) will not lower the impedance.
  • Resin-coated core to protect cables.
  • Impedance is stable from -40°C~+140°C, with a high Curie temp.
  • Possible to suppress normal mode noise.
