The 75 Ohm impedance and RG-59 cable group target it for video surveillance, broadband, and in-building distribution where plenum-rated cable is required by code. ## What the 75 Ohm Rating and Cable Match Mean 75 Ohm is the standard impedance for composite video, CCTV, and broadband RF — not the 50 Ohm used in cellular or Wi-Fi. The 142335-75 is explicitly listed for RG-59 plenum cable, 20 AWG center conductor. The plenum rating means the jacket material meets fire code for air-handling spaces (above drop ceilings, in ventilation ducts). ## Kit Contents and Termination The package includes three pieces: the SMB plug body, one center contact, and one ferrule. The snap-on fastening is standard for SMB — push to mate, pull to unmate — rated for 500 cycles. The gold plating on both the body and center contact supports that cycle life without corrosion in indoor or conditioned environments. ## Insertion Loss and Signal Path Insertion loss is listed at 0.3 dB. For a 75 Ohm video path, that's a clean number — it won't visibly degrade a composite or HD-SDI signal over a short cable run. The single-port, plug configuration mates with any standard SMB jack (bulkhead or PCB-mount) of the same impedance. The snap-on coupling gives a quick connect/disconnect for field-service or test points where you don't want to unscrew a threaded connector.","metaTitle":"Amphenol RF 142335-75 SMB Mini Plug, 75 Ohm, RG-59","metaDescription":"Amphenol RF 142335-75 SMB mini plug, 75 Ohm impedance, for RG-59 plenum cable.
