For sub-6 GHz work (cellular, Wi-Fi, ISM bands) this jack has headroom; for Ku-band satellite links at 12–18 GHz, it's at the rated ceiling. The 500 V rating comes from the PTFE dielectric's breakdown strength, not the contact spacing — relevant if DC bias or high RF voltage is present on the line. ## 500 Mating Cycles with Gold-Plated Beryllium Copper 500 cycles is typical for a gold-over-beryllium copper contact in an SMA jack. The beryllium copper spring maintains contact force through temperature cycling and repeated matings. For a test-bench or field-service connector that sees regular connect/disconnect, this cycle life matches the duty. ## Bulkhead Mount with Solder Termination Center contact termination is solder — the installer tins the center conductor of the coaxial cable and solders it into the pin. The through-hole solder cups on the shield legs provide strain relief for the cable braid.","metaTitle":"Amphenol 132291-12 SMA Jack, 50 Ohm, 18 GHz, Bulkhead","metaDescription":"132291-12 Amphenol RF SMA jack, female socket, 50 Ohm, 18 GHz, 500 V, 500 mating cycles, gold body.
