Barrier Strip Filtered Terminal Blocks

EMI Filtered Arrays

The barrier strip filtered terminal block is designed provide EMI/RFI filtering of AC and DC power lines and control lines. These filtered terminal blocks are available in various sizes with terminal for soldering or spade lugs.



  • UL recognized and CSA approved for DC voltages
  • E133076, UL 1059
  • LR92537, CSA STD 22.2 N°158-1987 and ECN584B
  • Filter element provides high insertion loss for EMI/RFI filtering of AC and DC power and control lines
  • Rugged construction provides protection to filtering element; especially useful for repeated changes in wiring or field connections
  • 2 to 6 terminals available (combine if larger number of terminals needed)
  • Cost-effective solution for industrial interconnection EMI filtering problems
  • Termination options available: straight lead, male or female disconnects, and value added wiring
  • RoHS Compliant with exemption 7. Fully compliant versions available.
