DATASHEET Common-mode Chokes RN series
Current-compensated Chokes
Rated currents from 0.3 to 10 A Approvals
DC to 400 Hz frequency
100 kHz to 3 MHz common-mode resonance
frequency
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
Performance indicators
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
suppression capacitors.
