The 75-Ohm impedance and 4 GHz frequency ceiling make this a video/broadband interconnect, not a generic 50-Ohm RF line — the impedance mismatch penalty is baked into the interface. ## Cable Fit and Termination — Crimp Shield, Solder Centre The shield terminates with a crimp — the braid is captured by the ferrule, not soldered — which gives a consistent, gas-tight connection across the cable group. The centre contact is soldered, so you need a controlled-temp iron for the pin, not a crimp tool for the signal path. ## Temperature Range and Mating Cycles The 500-cycle rating with gold-plated centre contact means this plug is built for field-service reconnects — not a one-time install. The snap-on fastening holds under vibration but releases with a firm pull, so it's not a lock-ring for high-shock environments.","metaTitle":"Amphenol RF 903-600P-71S SMB Plug, 75 Ohm, 4 GHz, Crimp","metaDescription":"903-600P-71S Amphenol RF SMB plug, 75 Ohm, 4 GHz, crimp termination for RG-179 cable.
