Description

Current reference data for BAC502: SMA · 50 Ohm · DC. The catalog currently lists the configuration as: Straight. Impedance is listed as 50 Ohm. If that parameter is critical, confirm it again in RFQ. Frequency is listed as DC. 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.
