Description
SMC Plug (Male) to SMA Jack (Female) | Straight Design | Screw-Lock | Brass Body
The ROSNOL AD-MC1A25A/933-93 is a precision RF adapter operating from DC to 10 GHz with 50 ohm impedance. It achieves a VSWR of ≤1.35 and insertion loss of ≤0.05 × √F GHz, ensuring excellent return loss performance. Electrical specifications include insulation resistance ≥1 GΩ, test voltage 750 Vrms, and RF leakage ≥90 dB up to 1 GHz. Screw-lock coupling provides secure engagement, with recommended torque of 0.25 to 0.35 Nm for SMC and 0.8 to 1.1 Nm for SMA. Mechanical durability is rated at ≥500 mating cycles.Engineered with premium materials, both sides use beryllium copper center contacts with gold plating over nickel-phosphorus underplating, brass bodies nickel plated, and PTFE insulators for dielectric stability. Coupling nuts are brass nickel plated for long-term reliability. The adapter operates reliably from −65°C to +165°C.
ROSNOL’s RF adapters deliver precision, consistency, and value, making them a competitive alternative to major European and American brands. All products are manufactured under ISO 9001 certified processes and comply fully with RoHS and REACH. Customization for materials, plating, and mechanical design is available to support specialized interconnect needs.
