Dual-choke configurations
Multiple PCB-mounting options
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.
