Product details

SMA Plug for RG-405 Semi-Rigid Cable

The 1-1478904-0: It is a 3-piece kit that includes the connector body, a gold-plated brass center contact, and a PTFE insulator — you solder the center pin and shield termination yourself. The 50 Ohm impedance and 18 GHz frequency ceiling place it in the standard SMA performance band, suitable for microwave test leads, module pigtails, and short-jump interconnects inside an instrument chassis.

Cable Fit and Assembly

This plug is built for RG-405 (.085" semi-rigid) cable — the common 0.085-inch diameter copper-clad steel coax used in RF assemblies where the cable holds its shape after bending. The center contact and shield are both solder-terminated, which is the standard method for semi-rigid: you strip the cable, solder the pin to the center conductor, and solder the shield to the connector body. The threaded coupling nut provides a vibration-resistant mate to any standard SMA jack.

Signal and Mechanical Ratings

Rated for 50 Ohms nominal impedance and 18 GHz maximum frequency, this plug holds the impedance through the launch when the cable prep and solder joint are clean. Voltage rating is 335 V, which is typical for SMA connectors at this impedance level.

Frequently asked questions

What cable does 1-1478904-0 work with?

This plug is designed for RG-405 (.085" semi-rigid) cable — the 0.085-inch diameter semi-rigid coax. The center contact and shield are both solder-terminated, so the cable prep determines the assembly quality.

Does 1-1478904-0 include a contact and insulator?

Yes, the 1-1478904-0 ships as a 3-piece kit: the connector body, one gold-plated brass center contact, and one PTFE insulator. You supply the RG-405 cable and solder.

What is the impedance of 1-1478904-0?

50 Ohms nominal, which is the standard impedance for SMA connectors. The 18 GHz frequency rating holds when the cable launch is properly prepared.
