Key Specifications
Description
TNC Jack ( Female ) Bulkhead Cable Connector for RG 179, DC- 4 GHz, VSWR ≤ 1.25, 75 Ω, with Crimped Cable Entry.
The TNC2CA70-G179-IG/H3 TNC Jack (Female) Isolated Ground Bulkhead Connector is a 50 Ohm RF connector designed for reliable signal transmission in communication, instrumentation, and electronic systems. Engineered for RG179 cable assemblies, this bulkhead-mounted connector operates from DC to 4 GHz and delivers a VSWR of 1.25 or better, helping maintain stable signal integrity across a wide frequency range. Its isolated ground design makes it suitable for applications requiring controlled grounding and dependable RF performance.
Constructed with a phosphor bronze center contact featuring gold plating over a non-magnetic nickel-phosphorus underplate, the connector provides excellent conductivity and durability. The nickel-plated brass body, coupling nut, and washer enhance mechanical strength, while the PTFE insulator and silicone rubber gasket support consistent electrical performance. Key specifications include insulation resistance of at least 5 GΩ, working voltage of 500 V rms, test voltage of 1500 V rms, and power handling of 80 W at 2 GHz.
The screw-lock coupling mechanism ensures secure mating and supports a minimum of 500 mating cycles. With crimp attachment for both the center and cable contacts, RoHS compliance, and an operating temperature range of -65°C to +165°C, the TNC2CA70-G179-IG/H3 is an excellent choice for professional RF interconnect, instrumentation, and panel-mount connectivity applications.
