  • Model: EV/EH series
  • Order code: EV-x-y-02-z
  • Brand:
  • Country: Germany
  • common mode suppression chokes are mainly used for filter noise on AC power lines. noise on commercial power lines could enter the requirement and disturb the proper function. noise generated by the equipment for example from switch mode power supplies need to be filtered and spread of such generated noise need to be suppressed. common mode suppression chokes together with line bypass capacitors building an AC EMI suppression filter device.

  • Model: RB series
  • Order code: RB xxxx-xx-xmx
  • Brand:
  • Country: Germany
  • RB common-mode chokes are mainly used to filter EMI noise on AC power lines up to 600 VAC but they are as well applicable in DC power lines of photovoltaic installations or similar applications up to 1000 VDC. EMI noise of electronic equipment can go to the power lines and disturb the proper function of other devices like TV sets or radios. Thus noise generated by the equipment from switched power electronics or by high slew rates of controllers needs to be filtered. RB common-mode chokes are used to suppress EMI noise in PCB integrated filter designs with line bypass capacitors or in combination with single phase filters for extra low leakage filter designs.

  • Model: RD series
  • Order code: RD xxxx-xx-xmx
  • Brand:
  • Country: Germany
  • RD 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 of the windings. These chokes are typically used in conjunction with suppression capacitors.

  • Model: RN series
  • Order code: RD xyy-z-t
  • Brand:
  • Country: Germany
  • 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 of the windings. These chokes are typically used in conjunction with suppression capacitors.
