Description

Current reference data for R191389400: SMA · 50 · 12.4. Impedance is listed as 50. If that parameter is critical, confirm it again in RFQ. Frequency is listed as 12.4. 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. Use this page to shortlist before RFQ, not as the final sign-off.
