Description

Current reference data for 73251-1900: 50 Ohms · 18 GHz · Bulkhead. The catalog currently lists the configuration as: Straight · Solder. Impedance is listed as 50 Ohms. If that parameter is critical, confirm it again in RFQ. Frequency is listed as 18 GHz. 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. 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.
