The FN 9233 IEC inlet filter combines an excellent IEC inlet and mains filter with excellent filter attenuation in a small form factor. Choosing the FN 9233 product line brings you the rapid availability of a standard filter associated with the necessary safety acceptances. Standard IEC connector filters are a practical solution helping you to pass EMI system approval in a short time. A wide selection on amperage ratings, output connections, mounting possibilities and filters for medical applications are designed to offer you the desired solution. For types with additional earth line choke please consult the FN 9233 E data sheet.

Features and benefits

  • Exceptional conducted attenuation performance, based on chokes with high saturation resistance and excellent thermal behavior
  • Rear/front or snap-in mounting
  • Optional earth line choke see FN 9233 E data sheet
  • FN 9233 B versions comply with the requirements of 1MOP acc. to  IEC/EN 60601-1 for creepage and clearance, leakage current and high potential testing
  • Wide mounting flanges available
  • Different output connections offering maximum flexibility for assembly
  • Custom-specific versions are available on request

Typical applications

  • Portable electrical and electronic equipment
  • Small to medium-sized machines and household equipment
