Description

Current reference data for BJ3157: Non-Constant · 500 MHz · Bulkhead - Front Mount. The catalog currently lists the configuration as: Straight · Solder. Impedance is listed as Non-Constant. 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. Mounting is listed as Bulkhead - Front Mount. If panel, bulkhead, or flange constraints matter, send the dimensions with the RFQ. Use this page to shortlist before RFQ, not as the final sign-off.
