PCB Mount
Filtered Terminal Blocks
The PCB mount filtered terminal block is designed to pro-
vide 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 equip-
ment, metering, industrial controls, instrumentation and
EDP equipment.
