Product details
The SMA-KR-R is an SMA Receptacle For Printed Circuit Board connector. This connector is suitable for various high-frequency applications. It features a impedance 50Ω, operates up to 28GHz, and has a rated voltage of AC 335V, ensures a high insulation resistance (5000MΩ(Min.) at DC 500V), a low contact resistance (3 mΩ(Max.), and an excellent V.S.W.R 1.7(Max.) at DC~28 GHz. Withstanding temperatures from -40 to +85°C. The contact is made of Beryllium Copper/Gold Plating, while the body is Brass/Gold Plating. We can customize our products for you. We offer total customization, including changes to a product's shape, length, material, surface treatment, and packaging. Available from 1 piece for in-stock items.Learn more about the SMA RF connector in our technical guide.

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
Reference MPN listed for SMA-KR-R. Final fit needs the drawing or BOM. If mounting is missing here, confirm it from the drawing or mating requirement. Material is listed as {'Contact': 'Beryllium Copper/Gold Plating', 'Body': 'Brass/Gold Plating'}. 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.
