Gold plating on the beryllium copper center contact handles repeated connect cycles — rated for 500 matings — without signal degradation. ## Ratings and Operating Envelope The 4 GHz ceiling covers L-band and S-band applications, including GPS, Wi-Fi, and cellular bands below 4 GHz. Insertion loss is held to 0.3 dB across the band, a tight spec for a crimp-style connector. Voltage rating is 335 V, which is generous for the signal levels typical on SMB links. ## Cable and Termination This kit is built for RG-178 and RG-196 — both 50 Ohm coax cables. The contact can be crimped or soldered; the shield termination is crimp-only via the included ferrule.","metaTitle":"TE 413985-6 SMB Plug, 50 Ohm, 4 GHz, Obsolete","metaDescription":"TE 413985-6 SMB plug, 50 Ohm, 4 GHz max, for RG-178/196 cable.
