Typical electrical schematic
Features and benefits 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.
