PCB Mount Filtered Terminal Blocks

Home>Coaxial Filters & Interconnects>Terminal Blocks

The PCB mount filtered terminal block is designed to provide excellent EMI/RFI filtering of low voltage DC power lines and control lines. These new terminal blocks use a unique screw clamp system with a wire protector which provides for quick and easy installation. Spectrum’s PCB Mount terminal blocks can be used for a variety of power supply filtering applications in telecommunications equipment, metering, industrial controls, instrumentation and EDP equipment.

PCB Mount Filtered Terminal Blocks Advantages

  • Filter element provides high insertion loss for EMI/RFI filtering of DC power and control lines
  • Rugged construction provides protection to filtering element; especially useful for repeated changes in wiring or field connections
  • 2 to 12 terminals available (combine if larger number of terminals needed)
  • Quick and easy PCB installation and maintenance
  • Cost-effective solution for industrial interconnection EMI filtering problems
  • Selectively loaded filter pins to economically meet exact filtering requirements
  • Available with European (5 mm) or US (.200") pin spacing
  • RoHS Compliant with exemption 7. Fully compliant versions available.
