Common Mode Chokes RN series

The RN series common-mode chokes are designed to attenuate common-mode or asymmetric interference signals. They are connected in series with the phase and neutral lines of an AC powerline input. Symmetrical components of noise are also attenuated by the leakage inductance. These chokes are typically used in conjunction with suppression capacitors, offering high saturation resistance, excellent thermal behavior, and a compact design with multiple PCB-mounting options. Custom-specific versions are available upon request.
