What This Adapter Does in the Signal Path
The Hirose BNC(75)J-H.FLJ-BPA-V(40) is a between-series adapter that converts a 75 Ohm BNC interface to an H.FL jack. It takes a BNC female socket on one end and presents an H.FL jack with a male pin on the other, letting you bridge standard 75 Ohm BNC cabling — common in video, broadcast, and broadband equipment — into an H.FL connection used on compact RF modules or internal board-level coax. The straight body keeps the signal path direct through the bulkhead, and the bayonet lock on the BNC side plus the snap-on H.FL mate give a secure, vibration-resistant connection.
75 Ohm Impedance and 3 GHz Bandwidth
Rated for 75 Ohms impedance and a maximum frequency of 3 GHz, this adapter is built for the 75 Ohm ecosystem — think video distribution, cable TV, SDI, and test equipment where the impedance match matters more than the raw frequency ceiling. The 3 GHz ceiling covers standard-definition and high-definition video signals comfortably, and the PTFE dielectric keeps the impedance stable across the band. The gold-plated phosphor bronze centre contact and nickel-plated zinc alloy body maintain signal integrity through repeated mates.
Panel Mount and Hardware Included
This adapter mounts through a panel bulkhead — the BNC jack side sits on the outside, the H.FL jack on the inside. The straight orientation keeps the cable entry perpendicular to the panel face, which simplifies routing in tight enclosures. The 500-cycle mating rating means it will hold up in field-service or test-bench use where connectors get swapped regularly.
