Product details

75 Ohm SMB Mini Jack for RG-179 — What's in the Kit

The Amphenol 142190-75 is a 75 Ohm SMB mini jack, male pin, built specifically for RG-179 double braid cable. It ships as a complete field-termination kit: one connector body, one center contact, one ferrule, and one piece of heat shrink. Snap-on fastening gives a quick, positive lock; the gold-plated brass body and gold-over-brass center contact handle 500 mating cycles without signal degradation.

This connector is designed for RG-179 double braid cable — the cable group is called out explicitly, so there's no guesswork about dielectric diameter or braid coverage. The included heat shrink covers the solder joint and ferrule for strain relief and insulation. The PTFE dielectric in the connector body matches the cable's dielectric for a consistent 75 Ohm impedance through the interface.

Frequently asked questions

Is 142190-75 compatible with RG-179 double braid cable?

Yes, the 142190-75 is specified for RG-179 double braid cable. The cable group is listed in the connector's specs, and the kit includes the ferrule and heat shrink needed for a proper shield termination.

Does 142190-75 include all necessary components?

Yes, it ships as a kit with 4 pieces: one connector body, one center contact, one ferrule, and one piece of heat shrink. You add the cable and solder.

Is 142190-75 a BNC connector?

No, it is an SMB mini jack, not a BNC. SMB uses a snap-on coupling and is smaller than a standard BNC. The 75 Ohm impedance and RG-179 cable size are common in video applications, but the interface is SMB, not BNC.
