Description

Current reference data for RFSMAA4PAAB: SMA Series · 50Ohm · Panel Mount. The catalog currently lists the configuration as: Compression. Impedance is listed as 50Ohm. If that parameter is critical, confirm it again in RFQ. Mounting is listed as Panel Mount. If panel, bulkhead, or flange constraints matter, send the dimensions with the RFQ. Material is listed as Stainless Steel Passivation. 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.

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.
