Description

Current reference data for AQJ-3700: QMA · 50 Ohm · DC. Impedance is listed as 50 Ohm. If that parameter is critical, confirm it again in RFQ. Frequency is listed as DC. The real operating limit still depends on the assembly, mating pair, and application context. 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.
