Description

Current reference data for 112239: 75 Ohms · 4 GHz · Bulkhead - Rear Mount. The catalog currently lists the configuration as: Straight · Cable - Crimp. Impedance is listed as 75 Ohms. If that parameter is critical, confirm it again in RFQ. Frequency is listed as 4 GHz. The real operating limit still depends on the assembly, mating pair, and application context. Mounting is listed as Bulkhead - Rear Mount. If panel, bulkhead, or flange constraints matter, send the dimensions with the RFQ. Material is listed as Brass. 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.
