Description

Current reference data for 85172747: N · 50 Ω · 703 MHz ... 803 MHz. Impedance is listed as 50 Ω. If that parameter is critical, confirm it again in RFQ. Frequency is listed as 703 MHz ... 803 MHz. 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 Aluminium / Black paint. 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.
