Common Mode Chokes RT series DATA SHEET Current-compensated Chokes Rated currents from 6 to 20 A Approvals & Compliances Up to 600 VAC and VDC 2- and 3-wire configurations Horizontal and vertical PCB mounting types Ruggedized saturation and thermal behavior RT common-mode chokes are mainly used to filter Open construction for forced and convection EMI noise on AC power lines up to 600 VAC. EMI cooling noise of electronic equipment can go to the power Straightforward pin-out for easy PCB design lines and disturb the proper function of other devices like communication devices or control logic of robotics. Thus noise generated by the equipment from switched power electronics or by high slew rates of controllers needs to be filtered. RT 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.
