Product details

MCX Snap-On Plug, 50 Ohm, 6 GHz — Field Termination for RG-174/316

The 919-101P-51SX: The gold-plated beryllium copper body and gold-over-brass centre contact support 500 mating cycles, making it suitable for test equipment, portable radios, and antenna pigtails where repeated connect-disconnect is routine.

Cable Group and Termination — Crimp Shield, Solder Centre

This plug terminates to RG-174, RG-188A, RG-316, LMR-100, and M17/119-RG174 cables.

Voltage and Impedance — 335 V, 50 Ohm

Rated 335 V and 50 Ohm nominal impedance. The 50 Ohm impedance matches the standard for RF signal chains — any mismatch at the connector launch will reflect energy back and increase VSWR, so keep the cable impedance and the PCB trace impedance at 50 Ohm for a clean pass-through.

Frequently asked questions

What is the Amphenol RF 919-101P-51SX connector?

The gold-plated beryllium copper body and gold-over-brass centre contact handle 500 mating cycles. It terminates to RG-174, RG-188, RG-316, and LMR-100 cables via a crimp shield and solder centre contact.
