Description

Current reference data for 031-70543-12G: 75 · 12 · Straight. The catalog currently lists the configuration as: Straight · Crimp. Impedance is listed as 75. If that parameter is critical, confirm it again in RFQ. Frequency is listed as 12. The real operating limit still depends on the assembly, mating pair, and application context. For higher-frequency projects, include the drawing, cable path, and critical requirements in the first RFQ. 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. The catalog also lists a sealing or protection value of Not Rated. Check that against the real environment requirement in RFQ. Use this page to shortlist before RFQ, not as the final sign-off.
