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.

Features Applications
  • High saturation resistance and excellent thermal behavior
  • Through-hole pin connections
  • Dual-choke configuration
  • Small compact design
  • Multiple housing options
  • Phase-angle control circuits in combination with saturating chokes
  • EMI input filters
  • For suppressing equipment with no earth connection
  • Suppressing high interference levels

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.

Features Applications
  • Rated currents up to 5 A
  • Compact and light weight
  • Low magnetic leakage flux
  • Sectional winding
  • Standard foot print
  • Broad range of available inductances and current ratings
  • Input filters for switching mode power supplies
  • Filters to reduce leaking noise
  • TVs, VCRs, multimedia and audio equipment
  • Office automation, communications and other electronic devices
  • Electric ballast
  • AC/AC converters
