RN EMC/EMI Chokes Schaffner RN current-compensated EMC/EMI Chokes attenuate common-mode or asymmetric (P/N to E) interference signals via connection to an AC powerline input. Features and benefits of Schaffner's RN Series current-compensated Chokes include high saturation resistance and excellent thermal behavior, through-hole pin connections, dual-choke configuration, small compact design, multiple housing options, and custom-specific versions available upon request. These chokes offer rated currents from 0.3A to 10A, DC to 1kHz frequency, and 100kHz to 3MHz common-mode resonance frequency. Typical applications for RN Chokes are phase-angle control circuits in combination with saturating chokes, EMI input filters, suppressing equipment with no earth connection, and suppressing high interference levels.
