Description

Current reference data for BJ28: 50 Ohms · 500 MHz · Straight. The catalog currently lists the configuration as: Straight · Quick Connect. Impedance is listed as 50 Ohms. If that parameter is critical, confirm it again in RFQ. Frequency is listed as 500 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. Use this page to shortlist before RFQ, not as the final sign-off.
