DATASHEET Common-mode Chokes RC series Current-compensated Chokes Rated currents from 0.25 to 0.7 A Approvals & Compliances DC to 400 Hz frequency 100 kHz to 3 MHz common-mode resonance frequency Dual-choke configurations Multiple PCB-mounting options RC 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 Performance indicators suppression capacitors.
