PCB Mount
Filtered 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. API’s Spectrum
Control line of 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.
