Product Information

RN Series

Product Overview

The RN102-1-02-3M0 from Schaffner is a current compensated common mode choke. It is an attenuating common mode or asymmetric (P/N –> E) interference signal by being connected in series with phase and neutral lines of an AC powerline input. Symmetrical components of noise are also attenuated by leakage inductance (stray inductance) of the windings. This choke is typically used in conjunction with suppression capacitors. It has high saturation resistance and excellent thermal behaviour. It is typically used in switch mode power applications, suppressing common mode interference levels, EMI input filters, suppression equipment with no earth connection and phase angle control circuits in combination with saturating chokes. This common mode choke is approved by VDE, UL 1283 and IEC/EN 60938-1 standards.
