Description

Current reference data for VB519: BNC · 50Ohm · 4 GHz. The catalog currently lists the configuration as: Straight · Receptacle. Impedance is listed as 50Ohm. 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 Flange 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.

Use this page to shortlist before RFQ. MOQ 200+ custom production and supply path are confirmed after drawing/spec/BOM review; no spot stock is assumed.
