DATASHEET Common-mode Chokes RB series
Current-compensated Chokes
Rated currents from 16 to 50 A Approvals
Up to 600 VAC or 1000 VDC
2- and 3-wire configurations
Horizontal and vertical PCB mounting types
Ruggedized saturation and thermal behavior
Open construction for forced and convection
cooling
Straightforward pin-out for easy PCB design
RB common-mode chokes are mainly used to filter
EMI noise on AC power lines up to 600 VAC but they
are as well applicable in DC power lines of
photovoltaic installations or similar applications up
to 1000 VDC. EMI noise of electronic equipment can
go to the power lines and disturb the proper function
of other devices like TV sets or radios. Thus noise
generated by the equipment from switched power
electronics or by high slew rates of controllers needs
to be filtered. RB common-mode chokes are used to
suppress EMI noise in PCB integrated filter designs
with line bypass capacitors or in combination with
single phase filters for extra low leakage filter designs.
