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

Current reference data for SMB-R-PC: 50 Ohms · Through Hole. Impedance is listed as 50 Ohms. If that parameter is critical, confirm it again in RFQ. Mounting is listed as Through Hole. If panel, bulkhead, or flange constraints matter, send the dimensions with the RFQ. 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.
