Key Specifications
Description
TNC Plug (Male) to UHF Jack (Female) | Straight Design | Screw-Lock | Brass Body
The ROSNOL AD-T1U25A/H44-H4 offers reliable RF performance from DC to 300 MHz with 50 Ω impedance (UHF non-constant). It achieves VSWR ≤1.30 and provides stable signal transmission for low-frequency applications. Electrical specifications include insulation resistance ≥5 GΩ, center contact resistance ≤1.5 mΩ (TNC) and ≤5 mΩ (UHF), and outer contact resistance ≤1 mΩ and ≤5 mΩ respectively. Rated for 500 V RMS working voltage, it supports secure coupling with screw-lock mechanisms on both ends, ≥500 mating cycles, and center contact captivation ≥28 N (TNC) and ≥30 N (UHF).
The adapter features phosphor bronze contacts with gold plating over nickel-phosphorus underplating for optimal conductivity. Bodies and coupling nuts are brass with copper-tin-zinc alloy finish, and insulators are PTFE for excellent dielectric properties. A silicone rubber gasket ensures environmental sealing. Operating temperature ranges from -65°C to +165°C for dependable performance.
ROSNOL’s precision-engineered RF adapters deliver consistent performance across high-frequency applications. Manufactured in ISO 9001-certified facilities and fully compliant with RoHS and REACH, they provide a cost-effective alternative to leading European and American brands. Customization for materials, plating, and mechanical design is available to meet specialized requirements.
