The shield terminates via crimp, the center contact is soldered. This is a 3-piece kit: the connector body, the center contact, and the crimp ferrule. Buyers ordering for a BOM line should count one kit per cable end — the ferrule is not sold separately under this code. The cable group covers RG-174, RG-188, RG-188A, RG-316, LMR-100, and M17/119-RG174, which are the common thin-diameter coax types for short-jump RF links, pigtail assemblies, and internal antenna feeds. The 919-101P-51S1X terminates with a solder center contact and a crimped shield ferrule. The beryllium copper body with nickel finish gives a corrosion-resistant shell; the silver housing color is the standard nickel plating, not a special finish. ## Thermal and Voltage Headroom The voltage rating of 335 V is the breakdown-limited figure for the MCX air gap at sea level — in practice, the limiting factor at 6 GHz is the insertion loss of 0.1 dB, not the voltage standoff.","metaTitle":"919-101P-51S1X MCX Plug, 50 Ohm, 6 GHz, RG-174 Cable Kit","metaDescription":"Amphenol RF 919-101P-51S1X MCX plug, male pin, 50 Ohm, DC-6 GHz, 0.1 dB insertion loss.
