Description
BNC Jack (Female) to SHV Jack (Female) | Straight Design | Bayonet-Lock | Brass Body
The ROSNOL AD-B2SV25A/H4-H4 is a precision RF adapter designed for DC to 300 MHz operation with 50 Ω impedance. It offers VSWR ≤ 1.30 (≥17.7 dB return loss) and supports operating voltage up to 3500 Vrms with adapter voltage handling of 500 V. Contact resistance is ≤1.5 mΩ on the BNC side and ≤2 mΩ on the SHV side; outer contact resistance ≤1 mΩ and ≤1.5 mΩ respectively. Coupling uses bayonet-lock on both sides for secure engagement, ensuring ≥500 mating cycles and axial captivation ≥28 N (BNC) and ≥27 N (SHV).Materials and plating: center contacts are phosphor bronze with 3 µin gold plating over 80 µin nickel-phosphorus underplating. Bodies are brass with copper-tin-zinc alloy plating; insulators are PTFE. Rated for −65 °C to +165 °C, this adapter provides excellent durability 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.
