Description
TNC Snap-On Plug (Male) to TNC Jack (Female) | Straight Design | Snap-Lock & Screw-Lock | Brass Body
The ROSNOL AD-TQ1T25A/H33-H3 is a precision RF adapter designed for systems operating from DC to 11 GHz with 50 Ω impedance. It delivers VSWR ≤1.25 (≥19.08 dB return loss) and insertion loss ≤0.05√F (GHz) dB for excellent signal integrity. Electrical ratings include insulation resistance ≥5 GΩ, center contact resistance ≤1.5 mΩ, and outer contact resistance ≤1 mΩ. The adapter withstands 250 V RMS voltage and 750 V RMS dielectric withstanding voltage. Coupling mechanisms include snap-lock on the TNC plug side and screw-lock on the TNC jack side, with ≥500 mating cycles and center contact captivation ≥15 N.The center contacts are phosphor bronze with gold plating over nickel-phosphorus underplating for superior conductivity and corrosion resistance. Bodies and coupling nuts are brass with nickel finish, while insulators are PTFE for excellent dielectric properties. A silicone rubber gasket enhances environmental sealing. Operating temperature ranges from -65°C to +155°C for dependable performance in harsh conditions.
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.
