SBSBJ-174LN-3 is a RG174 low noise 3 foot 50 ohm (0.91 meter) coax cable assembly with
a SMB plug (female contact) connector
on one end and
a SMB jack (male contact) connector
on the other
end.
This cable assembly has a
characteristic
impedance of 50 ohms.
50 ohm coax cable, connectors, and adapters are commonly used in wifi
(802.11 wireless LAN) antennas, ham transceivers, and other radio
frequency (RF) analog and digital signaling, microwave, radar,
hi-fidelity professional audio, non-destructive testing (NDT), oil and
petroleum production, ultrasonic transducers, accelerometers, strain
gauges, and some professional video applications.
This cable has a carbon-impregnated conductive
PVC
layer added around the
polyethylene
dielectric; this layer helps to increase shielding, dissipate static
charge, and reduce mechanically-generated electrical noise as the
cable is flexed. This extra protection is useful for long cable runs,
low-voltage signals, high-vibration environments, in applications
including aerospace, automotive, NDT, strain gauges and
accelerometers, and extremely high fidelity professional audio
production.
Low noise cable is generally not recommended for RF use, per a note in
Belden's 9239
datasheet. The datasheet doesn't give specifics, but in our
own testing, we see phase delay and impedance variations with
frequency that differ from ordinary cable. In the field, we've seen
mixed results in the GHz range; low noise cables seem to provide the
best results at signal frequencies below about 100 MHz.

We hi-pot test our cable assemblies for high-voltage breakdown
between core and braid. See About Hi-Pot
Testing for why this might matter to you, particularly for
physics or NDT applications. Caution: We make no claims as to the
safety of this product for high-voltage use. These voltages can
kill. Do not handle or approach any cable or conductor carrying
high voltage; this includes insulated cables, nearby metal parts,
water, and other conductive materials. Engineering and design for
safety in your application are your responsibility.
