Common Mode Chokes RD series
DATA
SHEET
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.
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
