Approvals & Compliances

RN chokes are attenuating common-mode or asymmetric (P/N –> E) interference signals, by being connected in series with the phase and neutral lines of an AC powerline input. Symmetrical components of the noise are also attenuated by the leakage inductance (stray inductance) of the windings. These chokes are typically used in conjunction with suppression capacitors.

Features and benefits

  • High saturation resistance and excellent thermal behavior
  • Through hole pin connections
  • Dual-choke configuration
  • Small compact design
  • Multiple housing options
  • Custom-specific versions are available on request
  • Higher temperature versions
  • Fully potted design usable for ruggedized applications

Typical applications

  • Switch-mode power applications
  • Suppressing common-mode interference levels
  • EMI input filters
  • For suppression-equipment with no earth connection
  • Phase-angle control circuits in combination with saturating chokes
