The body is nickel-plated brass; the center contacts are gold-plated beryllium copper, good for the 30 mating cycles this adapter is rated for. ## Obsolete — Sourcing Reality This adapter is listed as Obsolete. ## What the 6 GHz and 50 Ohm Ratings Mean The 50 Ohm impedance matches the standard for RF test equipment, antennas, and most module ports. The TNC side uses a threaded coupling for a vibration-resistant connection; the U.FL side uses a snap-on latch, which is quick to mate but limits the reconnection count to 30 cycles.","metaTitle":"TNCJ-U.FLJ-PA(40) TNC to U.FL Adapter, 50 Ohm, 6 GHz","metaDescription":"TNCJ-U.FLJ-PA(40) between-series adapter: TNC jack to U.FL jack, 50 Ohm, DC to 6 GHz.
