Coaxial Connectors (RF)

Coaxial Connectors Rf covers the familiar threaded, bayonet, and snap-on interfaces used to carry RF signals between a cable, a PCB, and an enclosure. In practice buyers usually mean SMA, SMB, SMC, BNC, TNC, N-type, MCX, MMCX, U.FL-style board jacks, and sometimes F-type or 7/16 for higher power or outdoor gear. Sub-types matter more than the label suggests: straight versus right-angle, plug versus jack, bulkhead feedthrough, PCB edge-launch, crimp versus solder, and 50 ohm versus 75 ohm can turn a simple line item into a sourcing headache if the drawing is vague. These parts show up in wireless modules, GPS and cellular antennas, test leads, IoT gateways, radar and instrumentation, broadcast video, and aerospace or defense harnesses where vibration and plating wear are real concerns. Most engineers I work with check frequency range, VSWR, impedance, mating cycles, center contact material, plating, torque, and whether the connector is rated for the cable they actually plan to use. Procurement teams tend to ask about RoHS or REACH status, reel versus bag packaging, country of origin, and date code, because a cheap connector with poor plating or mixed lots can cost more in rework than it saves. The usual trade-off is price against lead time and traceability: authorized stock may cost more, while open-market deals can be fine for MRO but need tighter incoming inspection to avoid counterfeit or re-marked parts. If you are comparing alternates, send the exact mating interface, cable group, and application frequency, not just “SMA male.” For current stock and a quote, check availability at icxing.com.
