Common-mode Chokes RD series
DATASHEET
Current-compensated Chokes
Rated currents from 6 to 64 A
Approvals & Compliances
Up to 600 VAC or 850 VDC
DC to 400 Hz frequencies
Dual, triple and quad-choke configurations
RD 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.
