Description

Current reference data for 142158: 50 · 4 · Bulkhead - Front Mount. The catalog currently lists the configuration as: Straight · Solder. Impedance is listed as 50. If that parameter is critical, confirm it again in RFQ. Frequency is listed as 4. The real operating limit still depends on the assembly, mating pair, and application context. Mounting is listed as Bulkhead - Front 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. The catalog also lists a sealing or protection value of Not Rated. Check that against the real environment requirement in RFQ. Use this page to shortlist before RFQ, not as the final sign-off.
