75 Ohm SMB Jack for Video and Telecom Signal Paths
The 142146-75: This is the 75 Ohm variant of the standard SMB snap-on interface — the impedance is the key selection differentiator, matching 75 Ohm coaxial cable used in video distribution, baseband telecom, and broadcast equipment.
Snap-On Coupling and 500-Cycle Duty
Fastening is snap-on — the SMB push-on coupling engages with a tactile click and releases with a straight pull.
Through-Hole Solder Termination
The shield termination is listed as solder, meaning the four ground legs are designed for wave or hand solder, not a press-fit or crimp. The PTFE dielectric withstands soldering temperatures without melting or shifting, a practical concern when hand-soldering the center pin.
Single-Port, Bulk Packaging
This is a single-port jack, supplied in bulk packaging — loose pieces in a bag or box, not tape-and-reel. For low-volume builds or prototype runs, bulk is straightforward; for high-volume pick-and-place, the right-angle through-hole format is typically hand-placed or wave-soldered anyway.
