Coaxial Connectors (RF)

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.

Frequently Asked Questions

How do I know if an RF coax connector is genuine and not a refurbished or re-marked part?

Ask for traceable paperwork such as CofC, packing label photos, and date/lot codes, then verify the brand’s part number format and plating finish against the datasheet. For open-market buys, we recommend incoming inspection for plating wear, thread condition, contact resistance, and logo marking, because counterfeit RF connectors often fail mechanically before they fail electrically.

What should I specify besides SMA, BNC, or N-type when requesting a quote?

Include gender, orientation, mounting style, impedance, frequency, cable type if it is a cable connector, and plating or grade requirements. A right-angle SMA jack for RG-316 is not interchangeable with a PCB edge-launch jack, and the wrong callout can stall purchasing for days.

Is it better to buy sealed reels or loose bulk packaging for production?

If the parts are going to SMT or automated assembly, tape-and-reel or tray packaging is usually worth it because it protects contacts and keeps lot control clean. For bench repair or field service, bulk bags can be cheaper, but inspect for bent center pins and mixed date codes before you release them to the line.
