Need a custom version from drawing?
We coordinate supplier-qualified RF connector and cable assembly sourcing from drawings, samples, or BOM. Typical production lead time is 3–6 weeks after drawing/spec review; feasibility, MOQ, and fit are confirmed by RFQ.
Before RFQ Clear inputs speed up review. ⌄
- • Share the reference MPN and source brand if it matters.
- • Add the BOM and volume split for production projects.
- • Attach the drawing or the key fit requirements.

Description
Current reference data for 142321: 50 Ohms · 4 GHz · Straight. The catalog currently lists the configuration as: Straight · Cable - Solder. Impedance is listed as 50 Ohms. If that parameter is critical, confirm it again in RFQ. Frequency is listed as 4 GHz. The real operating limit still depends on the assembly, mating pair, and application context. If mounting is missing here, confirm it from the drawing or mating requirement. Material is listed as Brass. That is useful for review, but it does not replace full project stack-up confirmation. Use this page to shortlist before RFQ, not as the final sign-off.
Use this page to shortlist before RFQ. MOQ 200+ custom production and supply path are confirmed after drawing/spec/BOM review; no spot stock is assumed.

The SMBP-316/U is an SMB Straight Plug connector, designed for coaxial cables. This connector is suitable for various high-frequency applications.Fits RG-316/U,RG-187A/U,RG-174/U cables. It features a impedance 50Ω, operates up to 4 GHz, and has a rated voltage of AC 335V, ensures a high insulation resistance (1000MΩ(Min.) at DC 500V), a low contact resistance (3 mΩ(Max.), and an excellent V.S.W.R 1.2(Max.) at 100~2000MHz. Withstanding temperatures from -40 to +85°C. The contact is made of Beryllium Copper/Gold Plating/Soldering, while the body is Brass/Nickel Plating/Crimp.A crimping toolTA-16 or TA-17 is required for mounting. We can customize our products for you. We offer total customization, including changes to a product's shape, length, material, surface treatment, and packaging.Learn more about the SMB RF connector in our technical guide.
