TE Connectivity / Schaffner RT Series N Current-Compensated EMC/RFI Chokes

TE Connectivity / Schaffner RT Series N Current-Compensated EMC/RFI Chokes are optimized to filter EMI noise on AC power lines up to 600VAC. The chokes feature 2- and 3-wire configurations in horizontal and vertical PCB mounting types for application flexibility. The RT Series N also provides an open construction for forced and convection cooling with ruggedized saturation and thermal behavior. The chokes have an integrated nanocrystalline core for high performance at 10kHz and a straightforward pin-out for easy PCB design. The TE Connectivity / Schaffner RT Series N Current-Compensated EMC/RFI Chokes are RoHS compliant and ideal for various applications, including AC/DC filtering for midsize power range drives, photovoltaic (PV) inverters, fast chargers, electric vehicle (EV) charging stations, uninterruptible power supplies (UPS), switch-mode power supplies (SMPS), and more.
