RN Series Current-Compensated Chokes
Schaffner's RN chokes attenuate common-mode or asymmetric (P/N -> E) interference signals by being placed in series with the phase and neutral lines of an AC power input. Symmetrical components of the noise are also attenuated by the leakage inductance of the windings. These chokes are typically used in conjunction with suppression capacitors.

EV/EH Series Common-mode Suppression Chokes
Common-mode suppression chokes are mainly used to filter noise on AC power lines. Noise from commercial power lines often enters equipment and disturb the proper function. Also, noise generated by equipment such as switching-mode power supplies needs to be filtered and suppressed. Common-mode suppression chokes are combined together with line bypass capacitors building an AC EMI suppression filter device.
