Performance indicators
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.
