Description
BNC Plug (Male) to TNC Jack (Female) | Straight Design | Bayonet-Lock & Screw-Lock | Brass Body
The ROSNOL AD-B1T25A/H44-H4 is designed for 50 Ω systems, supporting DC to 4 GHz with VSWR ≤1.35 and insertion loss ≤0.05 × √F (GHz) dB. Electrical ratings include 1500 Vrms test voltage, 400 Vrms working voltage, and ≤80 W power handling at 2 GHz. Coupling uses bayonet-lock on BNC and screw-lock on TNC for secure fit. Mechanical endurance ≥500 cycles; axial captivation ≥15 N; torque 0.46–0.69 N·m.Center contacts: phosphor bronze, gold plated (3 µin) over nickel-phosphorus underplating (80 µin). Bodies and coupling nuts: brass with copper-tin-zinc alloy plating; PTFE insulators; silicone gaskets. Temperature range −65 °C to +165 °C ensures reliability and corrosion resistance.
ROSNOL delivers precision-engineered RF adapters for uncompromising performance in high-frequency and microwave applications. Manufactured under ISO 9001-certified processes, fully RoHS and REACH compliant, and offering cost-effective alternatives to leading brands. Customization for materials, plating, and mechanical design is available to meet specialized interconnect requirements.
