Description
SMC Jack (Female) to BNC Jack (Female) | Straight Design | Screw-Lock & Bayonet-Lock | Brass Body
The ROSNOL AD-MC2B25A/93-93 is engineered for RF systems requiring stable performance up to 4 GHz with 50 ohm impedance. It delivers a VSWR of ≤1.35 and insertion loss of ≤0.05 × √F GHz, ensuring optimal signal integrity. Electrical ratings include insulation resistance ≥1 GΩ, center contact resistance ≤5 mΩ on the SMC side and ≤1.5 mΩ on the BNC side, and outer contact resistance ≤2.5 mΩ and ≤1 mΩ respectively. Screw-lock coupling on the SMC side and bayonet-lock on the BNC side provide secure engagement, with mechanical durability exceeding 500 mating cycles.Materials and plating are optimized for conductivity and durability. Both sides feature beryllium copper center contacts with gold plating over nickel-phosphorus underplating, brass bodies nickel plated, and PTFE insulators for dielectric stability. The adapter operates reliably from −65°C to +165°C.
ROSNOL’s RF adapters deliver consistent quality and cost efficiency, making them a reliable alternative to leading European and American brands. All ROSNOL components are manufactured in ISO 9001 certified facilities and fully comply with RoHS and REACH regulations. Customization services for materials, plating, and mechanical design are available to meet specialized interconnect requirements.
