Description
Current reference data for 031-5557-RFX: 50 Ohms · 4 GHz · Straight. The catalog currently lists the configuration as: Straight · Cable - Crimp. 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.
