Description
N Bulkhead Connector | Screw-Lock | Brass Body
The N2FB50-3251A/H4 is a 50 Ohm N jack (female) straight bulkhead connector designed for RF and microwave applications that require stable signal transmission and secure panel mounting. Featuring a solder attachment with a solder cup terminal, this connector supports frequencies from DC to 11 GHz and delivers reliable performance in communication systems, RF assemblies, and test equipment. Its standard N interface allows straightforward integration into a wide range of high-frequency installations.
Engineered for dependable electrical performance, the connector provides a 50 Ω impedance, low insertion loss, and a VSWR of ≤1.17 (return loss ≥22 dB) from 1.5 to 5 GHz. These characteristics help maintain signal integrity and minimize reflection across demanding RF and microwave operating environments.
The center contact is manufactured from phosphor bronze with gold plating over a non-magnetic nickel-phosphorus underplating, while the body is constructed from brass with a copper-tin-zinc alloy finish. PTFE insulation enhances dielectric stability, and the screw-lock coupling mechanism supports durability through at least 500 mating cycles.
Typical applications include wireless communication equipment, antenna systems, RF test instruments, microwave assemblies, laboratory platforms, and industrial network infrastructure.
