Description

Current reference data for 22641553: SMA / jack (female) · 50Ω · 0 GHz ... 18 GHz. Impedance is listed as 50Ω. If that parameter is critical, confirm it again in RFQ. Frequency is listed as 0 GHz ... 18 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. 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.
