Need a custom version from drawing?
We coordinate supplier-qualified RF connector and cable assembly sourcing from drawings, samples, or BOM. Typical production lead time is 3–6 weeks after drawing/spec review; feasibility, MOQ, and fit are confirmed by RFQ.
Before RFQ Clear inputs speed up review. ⌄
- • Share the reference MPN and source brand if it matters.
- • Add the BOM and volume split for production projects.
- • Attach the drawing or the key fit requirements.

Description
Current reference data for 85172821: N · 50 Ω · 2000 MHz ... 2200 MHz. Impedance is listed as 50 Ω. If that parameter is critical, confirm it again in RFQ. Frequency is listed as 2000 MHz ... 2200 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. The catalog also lists a sealing or protection value of IP54. Check that against the real environment requirement in RFQ. 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.
