Low Frequency Sleeve Ferrite Cores: TRMH Series

Most suitable ferrite core for suppressing conductive noise at 1 MHz or less.

  • High impedance at less than 1MHz.
  • Increased impedance can be obtained by several turns.
  • Suitable for conducted emissions for the KHz ranges.
  • Operating temperature -40 ~ 85 °C
