Barrier Strip
Filtered Terminal Blocks
The barrier strip filtered terminal block is designed to
provide excellent EMI/RFI filtering of AC and DC power
lines and control lines. This terminal block is available in
various sizes, with terminals for soldering or spade lugs.
Application examples include filtering power supplies
in telecommunications equipment, metering, industrial
controls, instrumentation and EDP equipment.
