Current-compensated Chokes

n Rated currents from 0.3 to 10A

n DC to 1kHz frequency

n 100kHz to 3MHz common-mode

resonance frequency

n Dual-choke conﬁgurations

n Multiple PCB-mounting options

Typical applications

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.

n High saturation resistance and excellent

thermal behavior.

n Through hole pin connections.

n Dual-choke configuration.

n Small compact design.

n Multiple housing options.

n Custom-specific versions are available on

request.

n Phase-angle control circuits in combination

with saturating chokes

n EMI input filters

n For suppressing equipment with no earth

connection

n Suppressing high interference levels
