TE Connectivity / Schaffner RC Common-Mode Chokes

TE Connectivity / Schaffner RC Common-Mode Chokes are current-compensated chokes that attenuate common-mode or asymmetric interference signals by being connected in series with phase and neutral lines of an AC powerline input. Symmetrical components of the noise are also attenuated by the leakage inductance of the windings. TE Connectivity / Schaffner RC Common-Mode Chokes are typically used in conjunction with suppression capacitors. The series features rated currents from 0.25A to 0.7A.
