Product details

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.

Description

Reference MPN listed for SMB-BR. 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': 'Phosphor Bronze/Gold Plating', 'Body': 'Brass/Nickel 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.
