SMB Jack, 75 Ohm — What This Connector Is
The snap-on fastening gives a quick, secure mate without a coupling nut — typical for test points, patch panels, and internal RF interconnects where repeated connect/disconnect is expected. The gold-plated brass body and center contact, paired with a PTFE dielectric, keep signal loss low across the band; insertion loss is rated at 0.3 dB. With 500 mating cycles on the interface, this jack holds up in field-service or production-test setups where connectors see regular reconnection.
Obsolete — Sourcing Reality
No official successor order code is listed. For BOM lines that still call out this part, supply runs through the independent surplus and broker channel. If you are qualifying a replacement, the 75 Ohm SMB interface is the fixed constraint; a parametric search on impedance, frequency range, and body style will turn up active alternatives from the same connector class.
This jack mates with any standard 75 Ohm SMB plug (male cable connector or female jack) that uses the snap-on coupling interface. The through-hole mounting and solder-contact termination suit a PCB edge-launch or bulkhead mount — the center pin and shield solder to the board, with the shield termination handled by the outer shell. No crimp tool needed; the board footprint is the typical SMB through-hole pattern.
