It delivers a 50 Ohm impedance path rated to 18 GHz — the full bandwidth of the SMA interface, limited by the connector geometry rather than the contact. The threaded coupling ensures a vibration-resistant mate, and the gold-over-brass centre contact with gold stainless steel body gives corrosion resistance for field-deployed or lab-use RF assemblies. ## What's in the Kit — and Why That Matters for the Build That means you don't order a separate crimp terminal or loose insulator — the cable prep and solder assembly are the only steps. The contact termination and shield termination are both solder, so the build requires a controlled-temp iron and the correct solder preform for the centre pin. ## 500 Mating Cycles — Gold Plating Makes It Field-Serviceable For a permanent-install cable assembly, 500 cycles is far more than needed; for a lab patch cable or a portable radio interface, it means the connector outlasts the cable.","metaTitle":"Molex 0732510031 SMA Plug, 50 Ohm, 18 GHz, RG-402 Kit","metaDescription":"Molex 0732510031 SMA plug, male pin, 50 Ohm impedance, 18 GHz max, for RG-402 .141 semi-rigid cable.
