RT series - 1

Common-mode Chokes RT series i i inscHaFFner shaping electrical power Current-compensated Chokes I Rated currents from 6 to 20 A I Up to 600 VAC and VDC I 2- and 3-wire configurations I Horizontal and vertical PCB mounting types I Ruggedized saturation and thermal behavior I Open construction for forced and convection cooling I Straightforward pin-out for easy PCB design Performance indicators RT common-mode chokes are mainly used to filter EMI noise on AC power lines up to 600 VAC. EMI noise of electronic equipment can go to the power 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. Technical specifications I Cost-effective PCB designs for up to 32 A with forced cooling * I Compact size and light weight I Low magnetic leakage flux I Excellent winding insulation I Standardized foot print I Broad range of inductance ratings I Custom-specific versions on request * See RB Application Note for forced cooling Typical applications I AC and DC filtering for midsize power range drives, photovoltaic inverters, fast chargers, charging stations, UPS and switch mode power supplies I Filter with low leakage current noise or improved immunity against grid disturbances I Electronic devices, automation and (industrial) LED lighting I Communication devices I Medical and laboratory Equipment I Converters Typical electrical schematic **
