Approvals
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.
Features and benefits
High saturation resistance and excellent thermal
behavior
Through hole or wire connections
Dual, triple and quad-choke configuration
Up to 64 A quad configuration
Multiple housing options
Custom-specific versions are available on request
Typical applications
Phase-angle control circuits in combination with
saturating chokes
EMI input filters
For suppressing equipment with no earth
connection
Suppressing high interference levels
