MMCX Plug Kit for RG-174-Class Coax
The Amphenol RF 908-43300 is a field-installable MMCX plug kit built for 50 Ohm systems. It comes as three pieces: the plug body, a hex crimp ferrule, and a snap-on end cap. The kit is designed for RG-174, RG-188, RG-188A, RG-316, LMR-100, and M17/119-RG174 cables — the common small-diameter coax types used in short-run RF interconnects. Rated to 6 GHz, the connector uses a PTFE dielectric and gold-plated brass centre contact with a solder termination for the centre pin and a crimp termination for the shield.
Cable Compatibility and Assembly
The 908-43300 is explicitly listed for RG-174, RG-188, RG-188A, RG-316, LMR-100, and M17/119-RG174. These cables share a similar dielectric diameter and braid coverage, so the crimp ferrule and centre-pin solder cup are sized to match. The kit includes the end cap that snaps over the crimp area to protect the braid termination and give a finished appearance.
